In the reaction, C + O2 → CO2; ΔH = -94 kcal. What is the heat content (enthalpy) of O2?
A. -94 kcal
B. > -94 kcal
C. < -94 kcal
D. Zero
Answer: Option D
Solution(By Examveda Team)
The enthalpy of formation of an element in its pure state is zero .since it doesn’t require any energy to obtain this state ($$form$$) it is naturally occurring state of the element.\[\begin{array}{l} {O_2}\left( g \right) \to {O_2}\left( g \right)\\ \Rightarrow \Delta H = 0 \end{array}\]
