Thermodynamics, Gibbs Free Energy

Refere to online steam tables please.. and show clearly how would you cancel units.

1)G = (419.04 - 373* 1.3069)*18.01528/1000

= -1.233 KJ/mol

2) G = 0.01*18.01528/1000

= 1.802*10^-4 KJ/mol

3) G = (2865.6 - 473*7.3115)*18.01528/1000

= -10.678 KJ/mol

4) G = (2724.7-293*5.6141)*18.01528/1000

= 19.452 KJ/mol

Gibbs free energy decreases as temperature increase. It increases as pressure increases.
