A plot of logarithm of rate vs logarithm of concentration of the reactant in a first order reaction is straight line whose slope is `tan theta`, where `theta` is

A

`A. 45^(@)`

B

`B. 135^(@)`

C

`C. 90^(@)`

D

`D. log k`

Text Solution

Verified by Experts

The correct Answer is:
A
`(-dc)/(dt)=k.c` (for first order reaction)
` log((-dc)/(dt))=(1)logc+logk`
Slope of the straight line is `1` and hence `theta= 45^(@)`
