Question

Calculate the CH4 melting point (Tmp)and boiling point (Tbp) in °C; assumereversibility for both processes. At TmpHfus = 0.94kJ/mole and Sfus =10.4J/mole K; at Tbp Hvap = 8.2kJ/moleand Svap = 73.3J/mole K.   Will ratelifesaver high and fast! Thank you!

Explanation / Answer

melting point T = delH/delS = 0.94e3 / 10.4= 90.3846154 ~ 90 K boiling point: T = delH/ delS = 8.2 e3 J/mol / 73.3 J/mol/K = 111.869031 ~ 112K
