For the real gases reaction `2CO_((g)) + O_(2(g)) rarr 2CO_(2(g)), Delta H = - 560kJ`. In a 10L rigid vessel at 500K, the initial pressure is 70 bar and after reaction it becomes 40 bar. The change in internal energy is:

A

`-557 kJ`

B

`-530 kJ`

C

`-563 kJ`

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
B
`Delta E = Delta H - V (Delta P)` `= -560 + 30 = -530KJ`
