Answer:

A reaction is second order with respect to a reactant.

Rate =k[A]

2

(i) If the concentration of the reactant is doubled, the rate of reaction becomes 4 times .

(ii) If the concentration of the reactant is reduced to half, the rate of reaction becomes one fourth.

If a reaction is second-order with respect to a particular reactant, when the concentration of that reactant is increased by a factor of 4, the reaction rate will increased by factor 16.

<h3>How do we calculate the rate of second order reaction?</h3>

Rate of the second order reaction will depends on the concentrations of one second-order reactant or two first-order reactants as:
Rate(1) = k[A]²

If the concentration of reactant becomes 4 times the initial concentration then rate will be:

Rate = k[4A]²

Rate(2) = 16k[A]²

Rate(2) = 16Rate(1)

Hence rate will increased by 16 times.
