Problem

Which of the following statements(s) is/are true with respect of the following reaction at constant temperature. 
A2(g) + 3B2(g) ↔ AB2(g) +AB4(g)             K = 5.04 x 10  -5 at 25.0°C

i. At equilibrium the rate of the reverse reaction is faster than the rate of the forward reaction.
ii. Changing the concentration of reactants and products will NOT affect the value of K.
​iii. At equilibrium, the concentration of products is greater than the concentration of reactants.
