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

A

`1`

B

`2`

C

`3`

D

`4`

Text Solution

Verified by Experts

The correct Answer is:
C
`2NO(g) + Cl_(2(g)) rarr 2NOCl_((g))`
Rate `= K[NO]^(2)[Cl_(2)]^(1), :. O.R. = 2 + 1 = 3`
