For which of the following reactions `DeltaH` is less than `DeltaE` ?

Options

A. `"HCl"("aq")+"NaOH"("aq")to"NaCl"("aq")+"H"_(2)"O"(l)`
B. `"H"_(2)(g)+l_(2)(g)to2"Hl(g)"`
C. `N_(2)(g)+O_(2)(g) overset("Electricity")to 2"NO(g)"`
D. `N_(2)(g)+3"H"_(2)(g)to 2"NH"_(3)(g)`

Answer

D

Explanation

`DeltaH=DeltaE+Deltan_(g)RT`
e.g. `N_(2)(g)+3H_(2)(g)to"2NH"_(3)(g)`
