Question

. Define order of reaction​

Answer 1

Answer:

: a number that relates the rate of a chemicalreaction with the concentrations of the reacting substances : the sum of all the exponents of the terms expressing concentrations of the molecules or atoms determining the rate of the reaction — compare first-order reaction, second-order reaction, third-order reaction, ...

Answer 2

Explanation:

Either the differential rate law or the integrated rate law can be used to determine the reaction order from experimental data. Often, the exponents in the rate law are the positive integers: 1 and 2 or even 0. Thus the reactions are zeroth, first, or second order in each reactant.
