Question:-
For a thermodynamic cycle to be irreversible it is necessary that
Option (A)
∫(dQ/T) = 0
Option (B)
∫(dQ/T) < 0
Option(C)
∫(dQ/T) > 0
Option(D)
∫(dQ/T) ³ 0
Correct Option:
(B)
Question Solution:
∫(dQ/T) = 0 cycle is reversible
∫(dQ/T) < 0 cycle is irreversible and possible
∫(dQ/T) > 0, cycle is impossible since it violates the second law
