Identify the reaction for which DeltaH ne DeltaE.

Options

A. `S(rh ombic)+O_(2)(g)toSO_(2)(g)`
B. `N_(2)(g)to2NO(g)`
C. `H_(2)(g)+CI_(2)(g)to2HC1(g)`
D. `CO(g)+(1)/(2)O_(2)(g)toCO_(2)(g)`

Answer

D

Explanation

In the reaction `CO(g)+(1)/(2)O_(2)(g)toCO_(2)(g)`
`Delta`n=Moles of gaseous product -Moles of gaseous reactant `implies Deltan ne 0`
