A first order reaction is given as A to ...

A first order reaction is given as `A to ` products. Its intergrated equation is

A

`k=(2.303)/(t) log""(a-x)/(a)`

B

`k=1/tlog""(a)/(a-x)`

C

`k=(2.303)/(t)log""(a)/(a-x)`

D

`-k=1/tlog""(a-x)/(a)`

Text Solution

Verified by Experts

The correct Answer is:
C
For a first order raction,
`k=(2.303)/(t)log ""(a)/(a-x)`
where 'a'a is the initial concentratin and 'x' is the amount reacted in time 't'.
