A mixture of 2 moles of CO and 1 mole of...

A mixture of `2` moles of `CO` and `1` mole of `O_(2)`, in a closed vessele is ignited to convert the `CO` to `CO_(2)` if `Delta H` is the enthalpy change and `Delta U` is the change in internal energy then:

Text Solution

Verified by Experts

The correct Answer is:
`Delta H ltDelta U`
`2CO+O_(2)rarr 2CO_(2)` is a exothermic reaction, heat is evolved from the system i.e. energy is lowered, thus exothermic reaction occur spontaneously on account of decreases in enthalpy of system thus `Delta H gt Delta U`.
