A student performs the following reaction, starting with NO and H2 each at a concentration of 0.200 M and both products at a concentration of OM: 2 NO (g) + 2 H2 (g) N2 (g) + 2 H20 (g) At equilibrium, the concentrations of N0 and H2 are 0.037 M, the concentration of N2 is 0.019 M, and the concentration of H20 is 0.056 M. What is the equilibrium constant for the reaction? Be sure to report your answer to the correct number of significant figures. Do not report units in your answer.

A student performs the following reaction, starting with NO and H2 each at a concentration of
0.200 M and both products at a concentration of OM:
2 NO (g) + 2 H2 (g) N2 (g) + 2 H2O (g)
At equilibrium, the concentrations of NO and H2 are 0.037 M, the concentration of N2 is 0.019 M,
and the concentration of H20 is 0.056 M. What is the equilibrium constant for the reaction?
Be sure to report your answer to the correct number of significant figures. Do not report units in
your answer.
