asap
(a) The boiling point of H2S is 62C. By using Trouton's rule calculate the value of enthalpy of vapourisation of H2S and water. Takat didih H2S ialah 62C. Dengan menggunakan aturan Trouton, hitung nilai entalpi pengewapan H2S dan air. (3 marks) (b) Compare the value obtained in (a) to the standard enthalpy of vapourisation, vopH for H2S,18.67kJmol1 and water, 40.66kJ mol1. Explain the deviation observed between the calculated value and the standard value. Bandingkan nilai yang diperolehi dari (a) dengan nilai entalpi piawai pengewapan vopH untuk H2S,18.67kJmor1 dan air, 40.66kJ mol'. Terangkan sisihan yang berlaku diantara nilai kiraan dan nilai piawai. (4 marks) (c) Water vapour at 150C in a 150mL container at 1.00 bar pressure was allowed to expand to 200mL and simultaneously heated to 200C. Assuming the vapour behave ideally, calculate the entropy change after the expansion and heating of water vapour. Wap air pada 150C dalam satu bekas 150mL pada tekanan 1.00 bar dibiarkan mengembang kepada 200mL dan pada masa yang sama di panaskan ke suhu 200C. Dengan mengandaikan wap air bersifat unggul, hitung perubahan entropi selepas pengembangan dan pemanasan wap air Step by Step Solution
