Q 1117067889.     For the reaction, `2CO + O_2 → 2CO_2`; `ΔH = – 560 kJ`. Two moles of `CO` and one mole of `O_2` are taken in a container of volume `1 L`. They completely form two moles of `CO_2`, the gases deviate appreciably from ideal behaviour. If the pressure in the vessel changes from `70` to `40` atm, calculate the magnitude (absolute value) of `ΔU` at `500 K`. (`1` L-atm `= 0.1` kJ)
