The rate of the elementary reaction,
`2NO+O_(2)rarr 2NO_(2)`, when the volume of the reaction vessel is doubled:

Options

A. will grow eight times of its initial rate
B. reduce to one- eight of ils initial rate
C. will grow four times of its initial rate
D. reduce to one-fourth of its initial rate

Explanation

Rate = `k [NO]^(2) [O_(2)]^(1)`,
Concentration of each species are reduced by 1/2 on increasing volume to two times and thus rate becomes 1/8 times of initial rate .
