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

Answer» Correct Answer - c
`2NO_((g)) + Cl_(2(g)) to 2 NOCl_((g))`
Rate = `k[NO]^(2) [Cl_(2)]^(1) , therefore O.R. = 2 + 1 = 3`.
