For the reaction R rarr P, graph of [R] ...

For the reaction `R rarr P`, graph of [R] against time is found to be a striaght line with negative slope. What is the order of reaction ?

A

Second order

B

Third order

C

First order

D

Zero order

Text Solution

Verified by Experts

The correct Answer is:
D
For zero order reaction
`k=(1)/(t)[[A_(0)]-[A]]`
or `[A]=[A]_(0)-kt`
Hence plot of [A] vs t is a straight line with negative slope.
