  • 2A + B - production If conc. of A and B is double the initial rate from 0.3 s M to 2.4 s M and when the conc. of A is doubled the rate of r

For the reaction, 2A+B→ products, when the concentrations of A and B both wrere doubled , the rate of the reaction increased from 0.3 molL-1s-1  to 2.4 molL-1 s-1. When the concentration of A alone is doubled, the rate increased from 

0.3 molL-1 s-1 to 0.6 molL-1 s-1
Which one of the following statements is correct ?

A) Order of the reaction with respect to B is 2

B) Order of the reaction with respect to A is 2

C) Total order of the reaction is 4

D) Order of the reaction with respect to B is 1

\\r=K[A]^{x}[B]^{y} \\\\ \Rightarrow 8=2^{3}=2^{x+y}\\ \Rightarrow x+y=3 \ldots(1)\\ \Rightarrow 2=2^{x}\\ \Rightarrow x=1, y=2\\ \text {Order w.rt. } A=1\\ \text{Order w.rt. } B=2
