1.

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

Answer»

`DeltaH` is independent of the PHYSICAL state of the reactants of that compound
`DeltaH GT DELTAE`
`DeltaH lt DeltaE`
`DeltaH = DeltaE`

Solution :`Deltan_(g)=1-(3)/(2)=(-1)/(2)`,As `Deltan_(g)` is negative, thus `DeltaH lt DeltaE`.
