Assertion : The enthalpy change for the ...

Assertion : The enthalpy change for the reaction `CaO_((s))+CO_(2(g)) rarr CaCO_(3(s))` is calld enthalpy of formation of calcium carbonate.
Reason : The reaction involves formation of 1 mole of `CaCO_(3)` from its constituent elements.

A

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

B

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

C

If assertion is true but reason is false.

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
D
The enthalpy change for the given reaction is not an enthalpy of formation of calcium carbonate, since `CaCO_(3)` has been formed from other compounds, and not from its constituent elements.
