NEET Chemistry First Law Assertion Reason Question
Assertion (A): The internal energy change (∆U) of a system is path independent. | Reason (R): According to the first law of thermodynamics, the internal energy change is given by ∆U = q + w, which depends only on the initial and final states.
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
The assertion is true because internal energy change is determined by the initial and final states, not the path taken. The reason correctly explains this by referencing the first law's equation ∆U = q + w, which is path-independent.
