NEET Physics (general) MCQ Question
Type: MCQ-diagram based-Medium-Class 11
Consider a diagram showing the reaction pathway for the combustion of graphite in oxygen to form carbon dioxide. Which label correctly represents the standard molar enthalpy of formation for the product in this reaction?
A
ΔfH°(CO2, g)
B
ΔfH°(O2, g)
C
ΔfH°(C, graphite)
D
ΔfH°(CO, g)
Correct Answer
Option A
Detailed Explanation
The standard molar enthalpy of formation, ΔfH°, is for forming one mole of the compound from its elements in their most stable form. In this case, CO2 is formed from graphite and oxygen.
