Assertion: DeltaH and DeltaE are almost ...

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.

A

If both the assertion and reason are true and the reason is the correct explanation of the assertion.

B

If both the assertion and reason are true but reason is not the correct explantion of the assertion.

C

If the assertion is true but reason is false.

D

If assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
B
`N_(2)(g) + O_(2) hArr 2NO(g)` We known that `DeltaH=DeltaE+DeltanRT`
`DeltaN=2-2=0` . Hence, `DeltanRT=0` Therefore, `DeltaH=DeltaE`
