NEET Chemistry Batteries Assertion Reason Question
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.
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
A is true but R is false.
A is false.
Correct Answer
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.
