1At a certain temperature, 659 K, Kp for the reaction, N2O4(g) <=> 2 NO2(g), is 5.4 x 10-69. Calculate the value of DGo in kJ for the reaction at 659 K.

2Given the values of So given below in J/mol K and the values of ΔHfo given in kJ/mol, calculate the value of ΔGo in kJ for the combustion of 1 mole of propane to form carbon dioxide and gaseous water at 298 K.

S (C3H8(g)) = 271

S (O2(g)) = 204

S (CO2(g)) = 214

S (H2O(g)) = 184

ΔHfo (C3H8(g)) = -100

ΔHfo (CO2(g)) = -398

ΔHfo (H2O(g)) = -226
