Rate law if;

a. [A] is zero order

Rate law = k [products]

b. [A] is first order

Rate law = k [A] [Products]

c. [A] is second order

Rats law = k[A]^2 [products]

Doubling the concentration of each case will results to:

A. In reaction 1, when the concentration of A is doubled, it has no effect on the reaction. This is so because the reaction is not dependent on the concentration of the reactant A.

B. In reaction 2, when concentration of A is doubled, rate of reaction doubles. There is an increase in the rate of the reaction by a product of 2. This increases the reaction and more products formed.

C. In reaction 3, when the concentration of A is doubled, the rate of thsii reaction is quadrupled that is increases by four.
