The thermodynamic system comprises of entropy and enthalpy. Entropy change and enthalpy change tend to confuse many students studying chemistry.
The core difference between entropy and enthalpy in points form is that entropy is the measure of the degree of disorder while enthalpy represents the total heat content.
What Is Entropy?
Entropy is the degree of randomness or extent of a disorder in a chemical reaction. The second law of thermodynamics state that entropy of an isolated system will always increase.
Therefore, the randomness of a chemical reaction will increase when the number of molecules involved increases.
You should note that the reaction move towards a higher level of disorder when products used are greater than reactants.
What Is Enthalpy?
Enthalpy refers to the heat change when the reactions occur at constant pressure. Enthalpy is a state function which implies that the value will not change regardless of the chemical route taken to obtain the products
