Chemistry-Rate of Reaction
NEET Chemistry Rate of Reaction Assertion Reason Question
Type: Assertion Reason-assertion-Medium-Class 12
Assertion (A): The rate of a first-order reaction is dependent on the concentration of the reactant. | Reason (R): The plot of ln[R] vs time for a first-order reaction 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 but R is true.
Correct Answer
Option A
Detailed Explanation
In a first-order reaction, the rate is proportional to the concentration of the reactant, and the plot of ln[R] vs time is a straight line with a negative slope, indicating a direct relationship.
