Answer:

[tex]\dfrac{1}{2}[/tex]

Explanation:

Let assume that X and Y are the reactants of a given reaction.

Then the rate can be expressed as:

rate = k[X][Y]

Suppose the concentration of X is quadrupled and the rate is doubled.

Then. we have;

[tex]2 \times rate = k[4X]^{\dfrac{1}{2}} [Y][/tex]

So, the initial rate of the concentration will be [tex]\dfrac{1}{2}[/tex] when the concentration of the reactant is increased by a factor of two.
