Consider a reaction a G + bH rarr Products . When concentration of both the reactants G and H is doubled the rate increases by eight times . However when the concentration of G isdoubled keeping the concentration of H fixed the rate is doubled . The overall order of the reaction is :

Solution :(D) If order of REACTION w.r.t G is x and w.r.t H is y, then on doubling [G] and [H] the rate becomes 8 TIMES i.e
`2^(x) 2^(y) =8 "or " 2^((x+y))= 2^(3)`
`:. ` x+y=3
`:.` Order of reaction =3
