Assuming that the value of Delta S and Delta H will not change at different temperature
delta G = delta H - T delta S
Delta H = -167.14 + 384.25 X 0.638
Delta H = 78.01 KJ
New Delta G will be
Tempearure = (273.15+ 19.5) K = 292.65
Delta G = delta H - T delta S = 78.01 - 292.64 X 0.638 = -108.69 KJ mole
