What is molar enthalpy change?

Short Answer

Expert verified
Molar enthalpy change refers to the enthalpy change when amounts of reactants measured in moles react under constant pressure.

Step by step solution

01

Understanding Molar

The term 'molar' refers to a unit of amount in chemistry, and it is used to express amounts of a chemical substance that contains as many constituent particles, e.g. atoms, molecules, ions, electrons, or photons, as there are atoms.
02

Understanding Enthalpy Change

Enthalpy change is the difference in heat content from the start (Reactants) to the end (Products) of a reaction. This is the heat absorbed or evolved in a chemical reaction under constant pressure.
03

Combining the definitions

Now combine the understanding from steps 1 and 2. Molar enthalpy change refers to the enthalpy change when amounts of reactants measured in moles react under constant pressure.
