Consider an elementary reaction $$A(g)+B(g)\rightarrow C(g)+D(g)$$ If the volume of reaction mixture is suddenly reduced to $$\frac{1}{3}$$ of its initial volume, the reaction rate will become 'x' times of the original reaction rate. The value of x is :

A

3

B

$$\frac{1}{9}$$

C

9

D

$$\frac{1}{3}$$
