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
At constant volume `DeltaH = DeltaU + V DeltaP`
`implies -560 =DeltaU+10xx(-30)xx0.1`
`DeltaU=-530 " kJ"`
