Answer: D) The reaction rate will increase by a factor of four.

Explanation:

A\rightarrow products

Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.

given order =2 , thus rate law is:

R=[A]^2      (1)

On cutting the concentration of  A to half

R'=[\frac{A}{2}]^2      (2)

Dividing 2 by 1  

\frac{R'}{R}=\frac{1}{4}

R'=4R

A second order reaction varies with the square of the concentration of the reactant. Therefore, halving the concentration will reduce the rate of reaction by a factor of 4.
The answer is E.
