For the reaction A + B -> products, it is observed that: (1) On doubling the initial concentration of A only, the rate of reaction is also doubled and (2) On doubling the initial concentrations 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: (AIPMT 2009)
A.rate = k [A] [B]2✓ Correct
B.rate = k [A]2 [B]2
C.rate = k [A] [B]
D.rate = k [A]2 [B]
Explanation
When concentration of A is doubled, rate is doubled. Hence order with respect to A is one. When concentrations of both A and B are doubled, rate increases by 8 times hence order with respect to B is
