Question

For a reaction A+B C+D if the concentration of A is doubled without altering the concentration of B, the rate gets doubled. If the concentration of B is increased by nine times without altering the concentration of A, the rate gets tripled. The order of the reaction is

Accepted Answer

Correct answer: C. (c) : A+B C+D r=k [A ]^ [B ]^ (i) 2r=k [2A ]^ [B ]^ (ii) 3r=k [A ]^ [9B ]^ (iii) Dividing eqn. (ii) by eqn. (i) 2=2^ or, =1 Dividing eqn. (iii) by eqn. (i) 3=9^ or, 3=3^2 or, 2 =1 or, =1/2 ∴ Order of the reaction =1+ 12= 32
