For the reaction
`2CO +O_(2) rarr 2CO_(2), DeltaH =- 560 kJ`,
`2mol` of `CO` and `1mol` of `O_(2)` are taken in a container of volume `1L`. They completely form `2 mol` of `CO_(2)`. If the pressure in the vessel changes from `70` to `40atm`, find the magnetic (absolute) value of `DeltaU at 500K. (1 L-atm = 0.1 kJ)`

Explanation

To solve the problem, we will follow these steps:

### Step 1: Identify the given data
- The reaction is:
\[ 2CO + O_2 \rightarrow 2CO_2 \]
- The enthalpy change (\(\Delta H\)) for the reaction is \(-560 \, \text{kJ}\).
