Chemistry

The reaction N2O(g) + O2(g) NO2(g) +NO(g) has ΔHº = -42.9 kJ andΔSº = -26.1 J/K. Suppose 0.400 mol of N2O and 0.400 of O2 areplaced in a 8.00 L container at 400 ºC and this equilibrium isestablished. What percentage of the N2O has reacted? (Note: Assumethat ΔH and ΔS are relatively insensitive to temperature, so ΔHº298and ΔSº298 are about the same as ΔHº673 and ΔSº673 respectively.)Enter your answer with 2 significant digits.
