Question

14. What is the increase in entropy when 11.2 L of Oz
are mixed with 11.2 L of H, at STP?
(1) 0.576 J/K
(2) 5.76 JK
(3) 7.56 J/K
(4) 2.76 JK

the correct answer is 3 option
please help with the solution​

Answer 1

Answer:

Let us consider the entropy =2.303nRlog(

V

1

V

2

)

Putting all given values in equation,

=2.303×1×8.314×log(

11.2

22.4

)

Since,n=1

=2.303×1×8.314×log

2

1

Implies that

=5.76JK
