For the raction A+Brarr products, it is found that order of A is 2 and the order of B is 3. In the rate expression when the concentration of both A and B are doubled the rate will increases by a factor

Solution :Given `"Rate"_(1st) = K[A]^(2) [B]^(3) "" … (i)`
`"Rate"_(2nd) = K[2A]^(2) [2B]^(3) "" …. (ii)`
On DIVIDING equation (i) and (ii) we get
`("Rate"_(1st) )/("Rate"_(2nd)) = (K[A]^(2)[B]^(3))/(K4[A]^(2)8[B]^(3)) = (1)/(32)`
`therefore "Rate"_(2nd) = 32 XX "Rate"_(1st)`
