WebAll reactions tend towards a state of chemical equilibrium, the point at which both the forward process and the reverse process are taking place at the same rate. Since the forward and reverse rates are equal, the … WebThe rate of the forward reaction is equal to a rate constant for this reaction, kf, times the concentrations of the reactants, ClNO 2 and NO. Rate forward = kf (ClNO 2 ) (NO) The rate of the reverse reaction is equal to a second rate constant, kr , times the concentrations of the products, NO 2 and ClNO. Rate reverse = kr (NO 2 ) (ClNO) WebFor a reversible reaction the rate constant for forward and backward reaction are 2.38 * 10 ^ -4 and 8.15 * 10 ^-5 respectively. thermodynamically favorable compared with the reverse reaction and thus the relationship k1>=k2 maintains between the rate constants. Given that: forward reaction Kf = 2.38 X 10^-4 and Kb =8.15 X 10^-5; Kc= Kf/Kb. gordon gluckman urology
