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=DeltaE`

B

`DeltaHltDeltaE`

C

`DeltaHgtDeltaE`

D

`DeltaH` is independent of the physical states of reactants.

Text Solution

Verified by Experts

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