Equilibrium constant, Kc for the reaction, N2(g)+3H2(g) ⇌ 2NH3(g) ; at 500 K is 0.061 litre 2 mole^−2. At a particular time, the analysis shows that composition of the reaction mixture is 3.00 mol litre^−1, N2 ,2.0 mol litre^−1 H2 , and 0.5 mol litre^−1 NH3. Is the reaction at equilibrium? If not, in which direction does the reaction tend to proceed to reach equilibrium?
