For the gaseous reaction: `N_(2)O_(4) rarr 2NO_(2)`

A

`Delta H lt Delta E`

B

`Delta H = Delta E`

C

`Delta H = 0`

D

`Delta H gt Delta E`

Text Solution

Verified by Experts

The correct Answer is:
D
We know that `Delta H = Delta E + DeltaE + Delta n_(g)RT`
For reaction, `N_(2)O_(4) to 2NO_(2)`
`Delta n_(g) = 2 -1 = 1`
`:. " "Delta H = Delta E + RT" or " DeltaH > Delta E`.
