The rate equation for the reaction 2A + B C is found to be: rate k[A][B]. The correct statement in relation to this reaction is that the

JEE Main 2004 Chemistry question

The rate equation for the reaction is found to be: rate . The correct statement in relation to this reaction is that the

(1)unit of K must be
(2)values of k is independent of the initial concentration of and Correct
(3)rate of formation of is twice the rate of disappearance of
(4) is a constant

Answer: (2)

Solution

The rate constant depends only on temperature (and catalyst), not on the initial concentrations, option (2). (1) is false: for an overall second-order rate law, k has units . (3) is
