What does the enthalpy of reaction measure?
O A. The amount of energy required to raise the temperature of a
substance
O B. The amount of energy required to make a chemical reaction
happen
O c. The amount of energy that is used or released as heat in a
reaction
O D. The amount of energy stored in the chemical bonds of the
reactants

Respuesta :

The enthalpy of reaction measures the amount of energy that is used or released as heat in a reaction

How do we calculate enthalpy?

Enthalpy of a reaction will be calculated by using the below equation as:

ΔHrxn = Enthalpy of products - Enthalpy of reactants

From the above equation it is clear that enthalpy is the amount of heat that is released or absorbed during the reaction.

  • The amount of energy required to raise the temperature of substance is known as the specific heat.
  • The amount of energy required to make a chemical reaction happen is called activation energy.
  • The amount of energy stored in the chemical bonds of the reactants potential energy.

Hence, the amount of energy that is used or released as heat in a reaction is the enthalpy of reaction.
