Consider the reaction: N2(g) + 2O2 (g) <-> N2O4(g)

Write the equilibrium constant for this reaction in terms of the equilibrium constants, K1 and K2, for the reactions below:

N2O4(g) <-> 2NO2 (g) K1

1/2N2(g) + O2(g) <-> NO2(g) K2

For answers with both a subscript and a superscript, enter the subscript first. For example, enter K 2/1 if the first equilibrium constant should be squared.

K=
