2 moles of CO and 1 mole of O₂ are taken in a container of volume 1 litre to form 2 moles of CO₂ according to equation
2CO+O₂→2CO₂, ΔH=−560KJ.
In this process, pressure changes from 70 atm to 40 atm. Find out value of ΔU at 500 K.
[Given: gases deviates apprecially from ideal nature. 1 atm−litre=0.1 KJ].
A. −530 KJ
B. −500 KJ
C. −557 KJ
D. −560 KJ
