a)      Temperature

Exp:       It is a constant of particular reaction at a given temperature. It does not depend upon initial concentration of the reactants time of reaction and extent of reaction.

the rate constant depends on initial conc.of the reactants because by the formula of rate constant=initial conc./time taken to convert the reactants into products. It  depends on time also.

The rate constant will change with Temperature, use of catalyst and also when the unit of rate constant is changed. For zero order reaction ty/x =(y/x) C0/k or k = (y/x) C0/ty/x. Here also k does not change with change in C value.

Rate constant is directly proportional to temperature because as temp increases velocity of molecule increases and rate contant also increases

answer is `a` rate constant depends on temp. but not anuy other factor such as intial concentration.according to the formula it is the concentration at equilibrium
