Assertion: `DeltaH` and `DeltaE` are almost the same for the reaction. `N_(2)(g)+O_(2)(g) hArr 2NO(g)`
Reason: All reactants and products are gases.

Options

A. If the both assertion and reason are true and the reason is the correct explanation of the assertion
B. If both assertion and reason are true and the reason is not the correct explanation of the assertion
C. If assertion is true but reason is false
D. If both assertion and reason are false statements.

Answer

B

Explanation

`DeltaH= DeltaE+DeltanRt`
`Deltan` = change in number of moles of products and reactant species.
`N_(2(g)) + O_(2(g)) iff 2NO_(g)`
`Delta n= 2- 2 =0`
`DeltaH=DeltaE + 0xxRT " or " , DeltaH=DeltaE`
