Areaction occurs between reactants x and z. doubling the concentration of x while the concentration of z is constant doubles the rate. tripling the concentration of z while the concentration of x is constant does not affect the rate.

what is the rate law for this reaction?

The rate law is,  .

Solution:- Let's say the order of reaction with respect to Z and X is n and m respectively.

So, the rate law in general could be written as:

where k is the rate constant.

If we take a look at the given information then, Doubling the concentration of X while concentration of Z is constant doubles the rate. It means the reaction is first order with respect to X and hence the value of m is 1.

Tripling the concentration of Z while the concentration of X is constant does not affect the rate. Here the rate is independent on the concentration of Z. It indicates the reaction is zero order with respect to Z and so the value of n is 0.

So, the rate law will be, .
