The heat of reaction remains the same even if stoichiometric coefficients are changed.

True or False?

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.
