For the reaction$\text{2}\text{CO}\text{(g)}\text{+}{\text{O}}_{\text{2}}\text{(g)}\to \text{2}{\text{CO}}_{\text{2}}\text{}\text{;}\text{ΔH}\text{=}-\text{500 kJ}$. Two moles of$\text{CO}$and one mole of${\mathrm{O}}_2$are taken in a container of volume$\text{2}\text{L}$. They completely form two moles of$\mathrm{C}{\mathrm{O}}_2$, the gas deviate appreciably from ideal behaviour. If pressure in vessel change from$\text{35}$to$\text{20}\text{atm}$. Find the magnitude of$\mathrm{\Delta }\mathrm{U}\mathrm{ }\mathrm{a}\mathrm{t}\mathrm{ }500\mathrm{K}.$$\text{(Assume}\text{1}\text{L-atm}\text{=}\text{0}\text{.1}\text{kJ)}$
