Conisder a reaction `aG+bH rarr` Products. When concentration of both the reactants `G` and `H` is doubled, the rate increases eight times. However, when the concentration of `G` is doubled, keeping the concentration of `H` fixed, the rate is doubled. The overall order of reaction is

Options

A. 0
B. 1
C. 2
D. 3

Answer

D

Explanation

Order with respect to 'G will tow and with respect ot 'H' the order will be one.
Rate =`k[G]^(2)[H]^(1)`
When concentration of both G and H are doubled, the rate will increase eight times.
