A + bB 
Product, dx/dt = k [A]a [B]b . If concentration of A is doubled, rate is four times. If concentration of B is made four times, rate is doubled. What is relation between rate of disappearance of A and that of B ?
A
B
C
D
None of these
Text Solution
Verified by ExpertsThe correct answer is:
B
(i) As on doubling concentration of A rate become four time so a = 2.
(ii) On four time concentration of B rate become double so b = 
.
So, Given equation :
