Type: Assertion Reason-assertion-Easy-Class 12
Assertion (A): The order of a reaction can be determined by analyzing the plot of ln [R] against time. | Reason (R): For a first order reaction, the plot of ln [R] against time is a straight line with a negative slope.
A
Both A and R are true and R is the correct explanation of A.
B
Both A and R are true but R is not the correct explanation of A.
C
A is true but R is false.
D
A is false.
