Expert Solution
Step 1

Yes. It is correct to say that irreversible process degrades the performance in thermodynamic system.

Irreversible process are those in which a system cannot return to its initial state i.e. it cannot back to its original form from where it started. This happens due to the dissipation in the system. A system cannot return to its initial state if there is some kind of dissipation in the system. Suppose in a system there is a initial state (P,V,T) and after doing work there is some energy released in the surrounding then the system cannot brought back to its original (P,V,T) without doing external work and if external work is done there will be change in its energy. This dissipation decreases the efficiency of the system and degrades the performance.
