For the reaction `A+B to ` product , what will be the order or reaction with respect to A and B?

Options

A. 1 With respect to A and 2 with respect to B
B. 2 with respect to A and 1 with resoect to B
C. 1 with respect to A and 1 with respect to B
D. 2 with respect to A and 2 with respect toB

Answer

B

Explanation

Rate `=k [A]^(x ) [B]^(y) `
from exp . `(1) , 5xx10^(-4) = K [2.5xx10^(-4)]^(x)[3xx10^(-5 )]y..(i) `
from exp, `(2) , 4xx10^(-3 ) =k [ 5xx10^(-4) ]^(x) [6xx10^(-5) ]^(y) ..(ii) `
Dividing (ii ) by (i) , `(4xx10^(-3))/(5xx10^(-4)) = 2^(x).2^(y)=8`
from exp . (3) .`1.6 xx10^(-2) =k [1xx10^(-3)]^(x)[6xx10^(-5)]^(y)`
Dividing (iii ) by `(ii) ,(1.6xx10^(-2))/(4xx10^(-3))=2^(x)=4`
or x=2 , y=1
Hence , order with respect to A is 2 and with repsect to B is 1.
