We’re being asked to determine the equilibrium constant (K) at 298.15 K for the given reaction:

3 NO(g) → N2O(g) + NO2(g)


We can use the following equation to solve for ΔG˚rxn:


ΔG°rxn=ΔG°f, prod-ΔG°f, react

Problem Details

Given the values of ΔGf° given below in kJ/mol, calculate the value of ΔG° in kJ for the reaction:

3 NO(g) => N2O(g) + NO2(g)

ΔGf° (NO) = 84

ΔGf° (NO2) = 48

ΔGf° (N2O) = 107
