Question

PLZ GIVE EXPLANATION​

Answer 1

Answer:

to check the spontaneity of a process, check the change in entropy of the system only. If the value is negative ( in this case) , then the process is non spontaneous.

Answer 2

Explanation:

if ∆S of universe > 0 process is spontaneous

if ∆S of universe = 0 process is in equilibrium condition

otherwise process is nonspontaneous

for the given process

∆S of universe =

∆S of system + ∆S of surrounding

= -21.99 + 21.99 = 0

hence process is in equilibrium
