Assertion (A): In thermodynamic analysis, the concept of reversibility is that, a reversible process is the most efficient process.
Reason (R): The energy transfer as heat and work during the forward process as always identically equal to the energy transfer is heat and work during the reversal or the process. 
  • a)
    Both A and R are individually true and R is the correct explanation of A
  • b)
    Both A and R are individually 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 is option 'A'. Can you explain this answer?

Reversibility in Thermodynamics

Reversibility is a concept in thermodynamics that refers to the ability of a process to be reversed without leaving any trace on the surroundings. In other words, a reversible process can be run forward or backward with no change in the system or its surroundings.

Efficiency of a Reversible Process

Assertion (A): In thermodynamic analysis, the concept of reversibility is that a reversible process is the most efficient process.

This assertion is true. A reversible process is considered to be the most efficient process because it can be run in either direction without any loss of energy. In other words, a reversible process can theoretically achieve 100% efficiency. This is because all the energy put into the system is converted into work, with none of it being lost as heat.

Energy Transfer in a Reversible Process

Reason (R): The energy transfer as heat and work during the forward process is always identically equal to the energy transfer as heat and work during the reversal of the process.

This reason is also true. In a reversible process, the energy transfer as heat and work during the forward process is identically equal to the energy transfer as heat and work during the reverse process. This is because the process can be run in either direction with no change in the system or surroundings. Therefore, there is no net change in energy during the forward and reverse processes.

Explanation of the Assertion

Therefore, reason (R) provides a correct explanation for assertion (A). The efficiency of a reversible process is due to the fact that the energy transfer as heat and work during the forward process is identically equal to the energy transfer as heat and work during the reverse process. This means that a reversible process can theoretically achieve 100% efficiency, making it the most efficient process.

According to corrolories of Carnot ,the efficiency of all the engines is always less than that of the reversible engine. in reversible engine , there is no entropy generation, so the energy interactions in reverse direction is same as that of forward process.
