REAKSI EKSOTERM DAN ENDOTERM

REAKSI EKSOTERM DAN ENDOTERM

       I.            Tujuan

Mengidentifikasi reaksi eksoterm dan endoterm

    II.            Dasar Teori

a.       Perubahan Entalpi ()

Entalpi adalah perubahan kalor pada tekanan tetap yang merupakan fungsi keadaan. Perubahan entalpi suatu sistem dapat diukur bila sistem mengalami perubahan. Oleh karena itu, nilai perubahan entalpi tergatung pada keadaan akhir dan awal saja. Maka dapat dirumuskan:  () = H_akhir – H_awal

b.      Reaksi eksoterm

Adalah reaksi kimia yang melepas kalor atau sistem membebaskan energi. Kalor berpindah dari sistem ke lingkungan. Akibat perpindahan energi tersebut, kalor reaksi dari sistem berkurang dan entalpi sebelum reaksi lebih besar daripada setelah reaksi.

Oleh karena () = H_akhir – H_awal    dan   H_awal > H_akhir   maka,

Kanca Kenthel

 

            Senajan uwis kekancan kawit cilik, dheweke uga tangga desa, Lia lan Inday uwis kaya kanca kenthel. Bocah kui tansah lungguh jejer ing sekolah lan dolan bareng terus. Kekancane bocah loro kui apik tenan, yen Lia lagi duweni masalah, Inday bakal tansah ana lan dhukung Lia, ananging Inday duweni rahasia sing during diandharake dening Lia, menawa Inday duweni rasa tresna marang Bagus. Ing sawijining dina, Bagas, bocah paling bagus ing desane nyeraki Lia. Awale, Lia nanggapine biasa wae, namung nganggep yen Bagas kui kancane, ananging Bagas ngganggep yen Lia uga nduweni rasa dening Bagas.

            Mundak suwe, Bagas lan Lia mundak lengket. Inday sing durung dikandhani marang Lia babagan hubungane karo Bagas nyatane uwis ngerti dewe. Inday ndue rasa rapenak yen dheweke nyerak-nyerak Lia, uga ora kepenak atine yen deleng kancane nalika karo Bagas. Lia sing awale ora ngerti apa-apa banjur ngerti yen Inday ora gelem cerak utawa dolan karo Lia meneh. Ananging Lia mikire kancane kui lagi sibuk utawa kakean gawean.

            Sedina tekan seminggu, ora ketok sing jenenge Inday, dheweke kaya ilang saka pandhangane Lia. Ing sawijining dina, Lia teka ning omahe Inday .

“Tokk..Tokk...Tokk… Kula nuwun, menapa Inday wonten dalem ?”

Ibune sing ana ning sisih kiwa omah banjur teka lan mangsuli “Inday ki isih turu nduk, jarene awake lagi kesel”.

“Oooo, nggih, Bu, menawi mekaten kula tak wangsul mawon. Mangeh sanjangke Inday nggih, Bu menawi kula mriki madosi Inday” mangkono pesenne Lia marang Ibune Inday.

            “Iya nduk, ngko tak tekakke” Ibune Inday mangsuli banjur bali ning sisih kiwa omah njerengi klambi.

            Ing dalan bali, Lia ngroso yen kancane kui ora kaya biasane. Iki uwis seminggu dheweke ora dolan bareng kaya adat sabene, dene Lia yo ora ngrasa yen dheweke duwei kaluputan marang kancane. Lia bingung kudu kepiye, dheweke ngrasa yen kekancane karo Inay wis beda, ananging ora ngerti marga apa.

            Sorene, Inday wis tangi saka turu “Nday, wis tangi taa.. mau ki koe digoleki Lia, ning mbuh arep ngopo”.

            “O.. nggih Bu” Inday mangsuli kandane ibune banjur lunga. Ning atine dheweke reti yen Lia wis ngerasa menawa dheweki rada ngadohi Lia.

            Esuke ing sekolahan, Lia karo Inday ora lungguh jejer. Lia teka ning panggonane Inday banjur takon.

            “Nday, wingi aku ning omahmu loo.. Ning koe lagi turu” pitakone Lia marang Inday. Inday mangsuli

            “Lha ngopo koe ning omahku ? Awakdhewe kan iso ketemu ning sekolah to, Li” jawabe Inday atos banget. Inday kegawa rasa mangkel, dheweke sakjane ora gelem nglarani atine Lia, nanging piye meneh kui mau wis kebacut.

            “Lha aku yo bingung kudu piye, Nday. Lha koe meneng wae ket wingi karo aku. Lha koe ngopo to, Nday ?” pitakone Lia mau gawe Inday bingung kudu jawab opo.

            “Aku rapopo kok. Koe wae sing aneh, wong aku ra ngapa-ngapa kok malah dikira ngapa. Aku yo dadi bingun dewe to, Li”. Mangkono jawabane Inday kanggo ngalihke pitakone Lia, sakjane atine pingin ngomong jujur, ananging isih bingung kudu pie le arep ngomong.

            “Yauwis nek koe rapopo, aku seneng. Muga-muga koe ora koyo sing tak pikirke yo Nday”. Inday ora mangsuli ananging langsung lunga ninggalake kancane dhewekan ning ngarep kelas. Dheweke mikir kudu cepet-cepet ngomong karo Lia, opo sakjane sing ana ning pikirane Inday.

            Esuke, Inday mangkat gasik banjur lungguh ana panggonane karo Lia biyen. Lia uga mangkat gasik, dheweke bingung kudu lungguh ning endi. Inday banjur nyelokake Lia lan ngakon Lia lungguh jejer karo Inday. Lia seneng banget, opo sing ana ning pikirane wis balik kaya biyen, nalika bocah loro kui ora ndue masalah lan dadi kanca kenthel.

            ”Li, aku pengen cerita karo koe, kan awakedhewe wis sue ora cerita “ Inday ngawali omongan karo Lia.

            “Ana apa to Nday, koyoke kok apik banget ceritane”  pitakone marang Inday.

            “Pancen apik kok, apik nggo aku, rareti nek koe pie” wangsulane Inday.

            “Yo kowe arep cerita apa ta ? lek cerita wae sik dowooooo . . .” akone Lia nggo Inday.

            “Sakjane tanpo koe cerita karo aku babagan koe cerak karo Bagas aku wis reti kok. Salahku aku durung cerita karo koe babagan aku yon due rasa karo Bagas. Aku durung cerita karo koe. Kui salahku, aku yo ora pie-pie nek kowe cerak karo dheweke. Ananging mbuh ngapa kok aku dadi sebel karo koe. Aku njaluk ngapura yo, Li. Aku mung isih bingung kudu pie” mangkono mau ceritane  Inday marang Lia.

            “Aku ki sakjane ming kekancan karo Bagas, aku ora duweni rasa pie-pie kok. Youwis, sik uwis yo ben uwis. Nek sumpama kowe ra seneng aku cerak karo Bagas yo rapopo. Aku tak ngadoh, sik penting aku karo koe tetep kekancan koyo biyen” mangkono mau wangsulane, Lia wis seneng opo sing dadi pitakone ning atiwis kejawab.

“Ora kok Li, koe rapopo cerak karo Bagas. Aku wegah egois, rapopo ben awakdhewe wong telu kekancan apik. Aku ora bakal nesu kok karo koe. Tenan iki” Inday mesem karo Lia. Seneng menawa kekancane wong loro kui wis balik kaya biyen maneh. Wis ora ono sing ditutup-tutupi, kabeh wis kewiyak, byak. Wis ora ono masalah, ora ono meneng-menengan, kabeh wis pada ngerti lan ngerteni.

Suara hati

Kau pernah menjadi pangeran didalam hatiku

Kau pernah menghiasi hidupku

Kau juga pernah mengisi hidupku dengan cinta dan kasihmu

                Tapii . . .

                Semua sudah berbeda

                Mungkin kau telah menemukan yang menggantikanku dihatimu 

                Menemukan penawar luka yang pernah kutoreh tanpa sengaja

Aku berharap . . .

Dialah orang yang tepat untukmu

Semoga dia tidak pernah melakukan kesalahan yang pernah kulakukan

Yaitu membuatmu memilih berlalu

                Mungkin . . kau at pernah ingin tau

                Jika, sampai saat ini aku masih sendiri

                Bukan karna aku tak mampu mencari lagi

                Tapi, kumencoba benahi hatiku yang hancuurrr setelah kepergianmu

Meski . . perpisahan ini mengukir luka dalam

Tapi, tiada pernah rasa menyesal mencintaimu

Bagaimanapun, aku bahagia bersamamu

                Terimakasih  . .

                Untuk cinta sesaat itu

                Maafkan . .

                Atas luka yang tanpa sengaja kutoreh dalam hatimu J
