NEET Chemistry Batteries Assertion Reason Question
Type: Assertion Reason-assertion-Medium-Class 12
Assertion (A): In primary batteries, the chemical reaction occurs only once and the battery cannot be reused. | Reason (R): A practical battery should be reasonably light and compact with voltage not varying appreciably during use.
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.
Correct Answer
Option B
Detailed Explanation
While both statements are true, the reason for primary batteries being non-reusable is not due to their weight or voltage stability. The assertion refers to the irreversible nature of the reaction, unrelated to the practicality requirements mentioned in the reason.
