Question

In a closed vessel a mixture of two moles of carbon monoxide and one mole of oxygen is ignited to convert the carbon monoxide to carbon dioxide. If Δ H is the enthalpy change and Δ E is the change in internal energy, then

TestHub · Accepted Answer

Formation of C O 2 from C O is an exothermic reaction; heat is evolved from the system, i.e., energy is lowered. Thus, exothermic reactions occur spontaneously on account of decrease in enthapy of system. Thus, Δ E > Δ H .
