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)`,

A

`DeltaH` is independent of the physical state of the reactants of that compound

B

`DeltaH gt DeltaE`

C

`DeltaH lt DeltaE`

D

`DeltaH = DeltaE`

Text Solution

Verified by Experts

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