Question

The reaction, \[\ce{A -> Products}\], is a zero order reaction. To what extent will the rate of the reaction change if the concentration of A is trebled?

Answer 1

For a zero order reaction, the rate law is:

Rate = k[A]⁰ = k

This means the rate is independent of the concentration of reactant A.

The concentration of A is trebled (i.e., made 3 times)

But since the rate does not depend on [A], the rate remains the same.

∴ The rate will not change.
