What letter represents the enthalpy of reaction?

Answer : The letter represents the enthalpy of reaction is, 'H'

Explanation:

Enthalpy of a reaction : Enthalpy of a reaction is defined as the energy change which takes place when the reactants go to the products.

Enthalpy of a reaction is represented as, . In this, 'H' represent the enthalpy.

When the enthalpy of reaction is positive that means the heat is absorbed during the reaction.

When the enthalpy of reaction is negative that means the heat is released during the reaction.

That means,  when the enthalpy of reaction is negative then the energy is released and the reaction will be exothermic reaction.

when the enthalpy of reaction is positive then the energy is absorbed and the reaction will be endothermic reaction.

Hence, the letter represents the enthalpy of reaction is, 'H'
