A reaction 2A + B overset(k)rarr C+ D is...

A reaction `2A + B overset(k)rarr C+ D` is first order with respect to `A` and 2nd order with respect to `B`. Initial conc. `(t = 0)` of `A` is `C_(0)` while `B` is `2C_(0)`. If at `t` as `30` minutes the conc. of `C` is `C_(0)//4`, then rate expression at `t = 30` minutes is:

A

`(7C_(0)^(3)k)/(16)`

B

`(27C_(0)^(3)k)/(32)`

C

`(247C_(0)^(3)k)/(64)`

D

`(49 k C_(0)^(3))/(32)`
