What are the values of q , w , U , H , S , S surr , and S univ for the following a
What are the values of q, w, U, H, S, Ssurr, and Suniv for the following a constant pressure process for a system containing 0.708 moles of CH3OH ?
CH3OH(l, 23.0 C, 1.00 atm) CH3OH(g, 120.0 C, 1.00 atm)
Assume that the volume of CH3OH(l) is much less than that of CH3OH(g) and that CH3OH(g) behaves as an ideal gas. Also, assume that the temperature of the surroundings is 120.0 C.
Data:
Molar heat capacity for CH3OH(l), Cp,m = 81.1 J K1 mol1
Molar heat capacity for CH3OH(g), Cp,m = 44.1 J K1 mol1
Enthalpy of vaporization, vapH = 35.2 kJ mol1 at 64.7 C and 1.00 atm
Enter answers that are accurate to three (3) or more significant figures.
