For the reaction 2CO(g)+O(2)(g)rarr 2C...

For the reaction
`2CO(g)+O_(2)(g)rarr 2CO_(2), DeltaH=-500kJ.`
Two moles of CO and one mole of `O_(2)` are taken in a container of volume 2 L. They completely from two moles of `CO_(2)`, the gas deviate appreciably from ideal behaviour. If pressure in vessel change from 35 to 20 atm. Find the magnitude of `DeltaU" at "500K`. (Assume 1 L - atom = 0.1 kJ)
