Answer to Question #347655 in General Chemistry for cyrus

Question

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

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

Answer 1

1. ∆G_293° = 9.25 kJ/mol

∆G_393° = - 0.24 kJ/mol

∆G_423° = - 6.17 kJ/mol

2. ∆ G_298° = 1137.98 kJ/mol
