For a reaction `A + B to` Products, the rate of the reaction was doubled, when concentration of-A was doubled. When the concentration of A and B were doubled, the rate was again doubled. The order of the reaction with respect to A and B are respectively.

Options

A. 1,1
B. 2,0
C. 1,0
D. 0,1

Answer

C

Explanation

When the concetration of A was doubled, the rate of reaction is doubled with respect to first order reaction of A. But when the concetration of B was doubled the half life do not change, so the reaction is of first order.
