Answer 1

To find the reaction order of an equation we need to check the exponents in the rate law's equation, and in this question the rate law's equation is given as:

Rate = k[ClO2]^x * [OH]^y

This x and y are the exponents which will give us the answer about the reaction order

In the experiments we see an increase of OH which represents a first-order reaction, and the decrease of ClO2 represents a second-order reaction, so the rate law's equation is:

Rate = k[ClO2]^2 * [OH]

Therefore ClO2 has a reaction order of 2
