One mole of methane gas at 25ºC and one atm is heated to 1200ºC at constant pressure. Assuming ideal behavior, calculate the values of w, q, ΔU, and ΔH given that the molar heat capacity of ethane is given by Cp,m/R = 23.64 + (47.86E3 K-1) T + (-1.92E-5 K-2) T2over the temperature range of 298-2000 K. Repeat the calculation for a constant volume process. Is there anything noteworthy of ΔU & H for both situations? What is the reasoning behind that?
(Hint for the calculation of ΔU: use the ideal gas law to substitute the term you don't know for the term you do know.)
