Question:

A 100mL reaction vessel initially contains 2.60x10^-2 moles of NO and 1.30x10^-2 moles of H2. At equilibrium the concentration of NO in the vessel is 0.161M. At equilibrium the vessel contains N2, H2O and H2. What is the value of the equilibrium constant Kc for the following reactions?

2H2(g) + 2NO(g) <---> 2 H2O(g) + N2(g)
