For an irrevesible process,

A

`Delta S_(sys) + Delta S_(surr) = 0`

B

`Delta S_(sys) + Delta S_(surr) lt 0`

C

`Delta S_(sys) + Delta S_(surr) gt 0`

D

`Delta S_(sys) = Delta S_(surr)`

Text Solution

Verified by Experts

The correct Answer is:
C
An irreversible process is a spontanous process moving in one particular direction. Thus, according to the second law of thermodynamics,
`Delta S_(uni) = Delta S_(sys) + Delta S_(surr) gt 0`
How ever, for a reversible process which corresponds to an equilibrium situation, the sum of `Delta S_(sys)` and `Delta S_(surr)` is zero.
