The reaction, N2(g) + O2(g) 2NO(g) contributes to air pollution whenever a fuel is burnt in air at a high temperature. At 1500 K, equilibrium constant K for it is 1.0 × 105. Suppose in a case [N2] = 0.80 mol L1 and [O2] = 0.20 mol L1 before any reaction occurs. Calculate the equilibrium concentrations of the reactants and the product after the mixture has been heated to 1500 K.
