Enthalpy is a measure of the total heat content of a system, reflecting energy changes in chemical reactions at constant pressure, whereas entropy quantifies the disorder or randomness in a system, crucial for determining spontaneity.
The term Enthalpy in a thermodynamic system represents its total internal energy. When ever a work is done by the system, there is a decrease in its entropy and when ever some work is done on the system, energy is gained and thus its entropy increases. It keeps on changing whenever a sy...

How is enthalpy calculated? Enthalpy is calculated as the internal energy of a system plus the product of its pressure and volume (H=U+PV). 10 Can energy be converted completely from one form to another? While energy can transform between forms, factors like inefficiency and entropy prevent ...
How do enthalpy and entropy relate to endergonic and exergonic reactions? What are the reactants and the products of cellular respiration? True or false? In coupled reactions, endergonic reactions power exergonic reactions. What is the difference between an exergonic reaction and an endergonic ...
