For a reaction `2NO(g)+Cl_(2)(g) hArr 2NOCl(g)`.When concentration of `Cl_(2)` is doubled, the rate of reaction becomes two times of the original. When the concentration of `NO` is doubled the rate becomes four times. What is the order of the reaction

Options

A. 1
B. 2
C. 3
D. 4

Answer

C

Explanation

`2NO_((g))+Cl_(2(g))to2NOCl_((g))`
Rate = `k[NO]^(2)[Cl_(2)]^(1)`, :. Order = `2+1=3`
