For a reaction, `2A + B rarr 3C`, The rate of appearance of C at time 't' is `1.2xx10^(-4)"mol L"^(-1)s^(-1)`. Identify the rate of reaction.

A

`4xx10^(-5)"mol L"^(-1)s^(-1)`

B

`4.5xx10^(-1)"mol L"^(-1)s^(-1)`

C

`3.6xx10^(-4)"mol L"^(-1)s^(-1)`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A
`(d[C])/(dt)=1.2xx10^(-4)`
Rate of reaction `= (1)/(3)(d[C])/(dt)=(1)/(3)xx1.2xx10^(-4)`
`=4xx10^(-5)"mol L"^(-1)s^(-1)`.
