For the reaction
`2CO(g) +O_(2)(g) rarr 2CO_(2)(g) ,`
`DeltaH=-560 kJ mol^(-1)` In 1 litre vessel at 500 K, the initial pressure is 70 atm and after the reaction, it becomes 40 atm at constant volume of one litre. All the above gases show significant deviation from ideal behavious (1 L atm =0.1 kJ). the change in internal energy will be

A

`+10 kJ mol^(-1)`

B

`-557 kJ mol^(-1)`

C

`-106 kJ mol^(-1)`

D

`+106 kJ mol^(-1)`

Text Solution
