a. the enzyme fastens up the conversion of k to Q
b. the reaction has reached to its equillibrium that is the concentration of both k and q are samealso hence whwn an enzyme is added,it catalyzes the reaction meaning it acts as a catalyst which increases the rate of reaction without itself getting used up hence it makes the conversion of k to Q faster that removes equillibrium state and rate of forward reaction increases by manyfolds
