At constant `T`and`P`,Which of the following statements is correct for the reaction,
`CO(G)+(1)/(2)O_(2)(g)rarrCO_(2)(g)`,

Options

A. `Delta H` is independent of the physical state of the reactants of that compound
B. `Delta H gt Delta E`
C. `Delta H lt Delta E`
D. `Delta H = Delta E`

Answer

C

Explanation

`Delta n_(g)= 1 - (3)/(2)= (-1)/(2)`, As `Delta n_(g)` is negative, thus `Delta H lt Delta E`
