Answer to Question #336035 in General Chemistry for Mave

Question

For the reaction, H2O(l)⟶H2O(g), calculate ΔG at a) 20ºC, b) 100ºC and c) 150ºC.

Calculate the standard-free energy changes for the reaction 2MgO(s) + 2Mg(s) + O2(g) at 25ºC .

With solution

Answer 1

1) ∆G_293° = 78.80 kJ/mol

∆G_393° = 118.19 kJ/mol

∆G_423° = 123.85 kJ/mol

2) ∆G_298° = 1364.29 kJ/mol
