Answer:
True
Explanation: Heat of reaction stoichiometry
Also known as the Enthalpy is the change of chemical agents in a reaction that occurs at a constant pressure. It is a thermodynamic unit for measuring the amount per mole. The stoichiometric coefficient vi represents the degree to which a chemical species participates in a reaction like thermite reaction.
Fe 2 O 3 + 2 Al → Al 2 O 3 + 2 Fe.
