Question
1 mol of an ideal gas at 27oC is compressed reverssibly from 20 L to 2L. Find out ᐃS :-
Options
A.4.606 cal / k
B.-4.606 cal / k
C.-19.147 J / k
D.Both (2) & (3)
Solution
ᐃS = 2.303 nR log 
ᐃS = 2.303 × 1 × 8.31 log
ᐃS = - 19.147 J/K or - 4.606 cal/k
ᐃS = 2.303 × 1 × 8.31 log
ᐃS = - 19.147 J/K or - 4.606 cal/k
