For the reaction, 2CO+O22CO2;H=560 kJ . Two moles of CO and one mole of O2 are taken in a container of volume 1 L . They completely form two moles of CO2 , the gases deviate appreciably from ideal behaviour. If the pressure in the vessel changes from 70 to 40 atm , find the magnitude (absolute value) of U at 500 K.(1 Latm=0.1 kJ)
