Explanation / Answer

when you plot log(rate) vs log[reactant] , slope of the straight line graph will give the order of the reaction .

Look at the first plot. Here slope = 1.11

So, the reaction is 1st order with respect to concentration of I-. p= 1

from the second plot , slope = 0.856 ~1

So, the reaction is 1st order with respect to concentration of H2O2. q= 1

The rate law is :

Rate = k [I-][H2O2]
