Question

Assertion :In a constant pressure process if we neglect the friction between piston then we can definetly say that the process has to be reversible. Reason: Since there is always an equilibrium on piston due to constant pressure we can say that it is reversible process.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

The correct option is D Both Assertion and Reason are incorrect

A process is reversible only if its done slowly and at any point of time it is in complete equilibrium.

A constant pressure process does not ensure that process is slow or their is an equilibrium at every point.

Hence both the statements are incorrect.
