Solution :`aG + bH to ` Product
Suppose order of REACTION = n
When concentration of both C and H is DOUBLED then the increase by eight time
rate `=" k (reactants)"^n`
`(8) = k(2)^n`
`n = 3`
When concentration of G is doubled keeping the concentration of H fixed, the rate is double.
rate `prop[G]^1`
Than rate `prop[G]^1[H]^2`
