For the real gases reaction 2CO (g) + O 2 (g) 
2CO 2 (g) ; DH = – 560 kJ. In 10 liter rigid vessel at 500 K, the initial pressure is 70 bar and after the reaction it becomes 40 bar. The change in internal energy is :
Text Solution
Verified by ExpertsThe correct answer is:
B
At constant volume 
H = 
U + V Δ P
– 560 = 
U + 10 × (–30) × 0.1
U = –530 kJ
