Question

What is the work done on the gas in cyclic process ABCA 

(1) +773.7 J 

(2) –773.7 J 

(3) +4762.3 J 

(4) –4762.3 J

Answer 1

Correct answer is:  (1) +773.7 J

W_AB = 0

W_BC = –10 (4 – 2) 

= –20 atm. Lit 

W_CA = 2.303(40) log2 

= 27.636 atm. Lit 

W_total = 7.636 atm. Lit 

= 773.7 Joule
