Q1: The entropy of sublimation of a certain compound is 5.2 J K–1 mol–1 at its normal sublimation point of 72 °C. Calculate the vapour pressure (in torr) of the compound at 33 °C. Assume that the enthalpy of sublimation is constant.

I get 1586.851385 torr

Q2:

Compound       So (J K–1 mol–1)
A 20
B 96
C 74
D 36

At 298 K, ΔGo is 129 kJ / mol for the reaction

3A + 2B == 2C + 2D

Calculate ΔHo for this reaction in kJ / mol.

I get 138.536 for this one

Can anyone help me to check it?
