For the reaction A + B products, it is observed that : A. On doubling the initial concentration of A only, the rate of reaction is also doubled and B. On doubling the initial concentration of both A and B , there is a change by a factor of 8 in the rate of the reaction. The rate of this reaction is given by :
Options
- Arate =k[A][B]
- Brate =k[A]^2[B]
- Crate =k[A][B]^2
- Drate = k [ A ]^2[ ~B ]^2
Correct answer
C. rate =k[A][B]^2
Step-by-step solution
aligned Rate & = k [ A ][ B ]^2 & = k [2 ~A ][2 ~B ]^2 & = k 8[ ~A ][ B ]^2 aligned
