During the kinetic study of the reaction, 2A + B to C + D. Following results were obtained. Based on the above data which one of the following is correct?

Answer»

RATE = `K[A]^(2)[B]`
rate = `k[A][B]`
rate = `k[A]^(2)[B]^(2)`
rate = `[A][B]^(2)`

Solution :d) The rate law equation may be expressed as:
Rate = `k[A]^(p)[B]^(q)` Consider II and III.
`((0.3)^(p)(0.4)^(q))/((0.3)^(2)(0.2)^(q))= (2.88 XX 10^(-1))/(7.2 xx 10^(-2))`
`(2)^(q)= (2)^(2)` or q=2
Consider I and IV,
`((0.4)^(p)(0.1)^(q))/((0.1)^(p)(0.1)^(q)) = (2.4 xx 10^(-2))/(6.0 xx 10^(-3))`
`(4)^(p) = (4)^(1)` or p=1
rate =`k[A][B]^(2)`
