K is the equilibrium expression of the concentrations in the reaction. The general form of an equilibrium expression is:
For the reaction
2NO(g) + 2H2(g) ⇌ N2(g) + 2H2O(g)
it is determined that, at equilibrium at a particular temperature, the concentrations are as follows: [NO(g)] = 8.1 x 10 -3 M, [H2(g)] = 4.1 x 10 -5 M, [N2(g)] = 5.3 x 10 -2 M, and [H2O(g)] = 2.9 x 10 -3 M. Calculate the value of K for the reaction at this temperature.
