For the real gases reaction, 2CO(g)+O(...

For the real gases reaction,
`2CO(g)+O_(2)(g)to2CO_(2)(g),DeltaH=-560 kJ.` In 10 litre 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 :

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"`
