Question

does rate constant changes due to adding of catalysts?

Answer 1

These are all included in the so-called rate constant (k)- which is only actually constant if all you are changing is the concentration of the reactants. If you change the temperature or the catalyst, for example, the rate constant changes. This is shown mathematically in the Arrhenius equation.

Answer 2

Heya @User

______________________________
=No, addition of Catalysts does not change the value of rate constant (K)

=but it lowers the time of attainment of equilibrium by simultaneously catalysing both forward rxn and backward rxn

=K is a constant for a particular rxn at a particular temperature

=value of K changes with change in Temperature, but its value does not change with concentration
