The A in the diagram indicates +VE. The correct option is D.
What is enthalpy?
Enthalpy is the result of the pressure, volume, and internal energy of the system added together.
The diagram demonstrates that, as indicated in the previous response, Hrxn is positive since the enthalpy of the products is higher than the enthalpy of the reactants.
The enthalpy of a reaction is determined by comparing the total enthalpy (heat content) of the reaction's products to the total enthalpy (heat content) of its reactants.
Thus, the correct option is D. +VE.
