A mixture of 2 mole of CO and 1 mol of `O_(2)` is ignited. Correct relationship is

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`.
