in a reaction `A + B to` product , rate is doubled when the concentration of B is doubled and rate increases by a factor of 8 when the concentration of both the Reactants (A and B) are doubled ,Rate law for the reactions can be written as

A

Rate=k[A][B]

B

Rate `=k[A]^(2)[B]`

C

Rate `k[A][B]^(2)`

D

Rate `=k[A]^(2)[B]^(2)`

Text Solution

Verified by Experts

The correct Answer is:
B
`r=K[A]^(m)[B]^(n)`
wrt `B " " r 2^(n) n=1`
wrt `A notin B " " 2^(m)xx2^(1) m=2`
