For the reaction `A+B to ` Product following date are given Order of reaction will be:

Options

A. 1
B. 2
C. 3
D. 2.5

Answer

C

Explanation

`K[A]^(x) [B]^(y)`
`therefore "From expt (1)"1=K]^(x) ]^(y) .....(1)`
`"From expt (2)" 2=K 2^(x) ]^(y) .....(2)`
From expt (3) 8=`K 2^(x) 2^(y) ......(3)`
From `(eq(1))/(eq(2))" we have " 1/2=((1)/(2))^(x) therefore x=1`
`"From " (eq(2))/(eq(3))" we have " 2/8=((1)/(2))^(y) therefore 2^(2)=2y`
`therefore y=2`
`therefore "Order "=1+2=(3)`
