A reaction is of second order in A and first order in B.
How is the rate affected on increasing the concentration of A three times ?

Text Solution

Verified by Experts

A reaction is second order in A and first order in B
When the concentration of A is increased three times, (i.e) 3A, then
Rate `= k[3A]^(2)[B]`
`= 9k [A]^(2)[B]=0` (initial rate)
This shows the rate will increase 9 times to the initial rate.
