The rate expression for the reaction A (...

The rate expression for the reaction `A (g) + B (g) rarr C (g)` is rate = `kC_(A)^(2)C_(B)^(1//2)`. What changes in the initial concentrations of A and B will cause the rate of reaction to increase by a factor of eight?

A

`C_(A) xx 2, C_(B) xx 2`

B

`C_(A) xx 2, C_(B) xx 4`

C

`C_(A) xx 1, C_(B) xx 4`

D

`C_(A) xx 4, C_(B) xx 1`

Text Solution

Rate `= kC_(A)^(2)C_(B)^(1//2)`, Rate `= k[2C_(A)]^(2)[4C_(B)]^(1//2) = 4 xx 2[C_(A)]^(2)[C_(B)]^(1//2)`
