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 the constant volume `DeltaH= DeltaU +V DeltaP`
`implies -560 = DeltaU+ 10 xx (-30) xx 0.1 `
`implies Delta U= -530 kJ`
