Calculate Delta G at 298 K for the following reactions.

Ca(s) + CO2(g) + 1/2O2(g) -> CaCO3(s)

2KClO3(g) -> 2KCl(s) + 3O2(g)

CH4(g) + 3Cl2(g) -> CHCl3(g) + 3HCl(g)
Delta G^0f CHCl3 is - 70.4 kJ/mol

The following reactions are important ones in catalytic converters in automobiles. Calculate Delta G for each at 298 K.

2CO2(g) + 2NO(g) -> N2(g) + 2CO2(g)
2NH3(g) + 2O2(g) -> N2O(g) + 3H2O(g)

1 answer

For the first reaction:
Delta G = - 572.4 kJ/mol

For the second reaction:
Delta G = - 990.2 kJ/mol
