The following Topics and Sub-Topics are covered in this chapter and are available on MSVgo:
Chemical Thermodynamics is a crucial topic of both physics and chemistry. It studies the relationship between work, heat, and chemical reaction or physical change.
It is one of the branches of thermodynamics where the interaction of each molecule is considered to figure out the behaviour of a group of molecules.
Under equilibrium thermodynamics transformation of energy and matter is studied as soon as they reach the state of equilibrium.
When certain observations are made on a part of the universe, the rest of the universe is surrounding a thermodynamic system. The relationship can be expressed as the universe = system + surroundings. It can be divided into three:-
The characteristic feature of a system is known as thermodynamic properties. They identify the system’s state. Thermodynamic properties can be extensive or intensive.
The quantitative measure of stored energy in a system is called thermodynamic potentials. Potentials measure the energy change in a system. Potentials are used based on temperature and pressure.

The law states the fundamental physical quantities that characterize thermodynamic systems at thermal equilibrium such as energy, temperature, and entropy. It mainly tells us how, under different circumstances, these quantities react.
There are four rules of thermodynamics:-
There are fixed values of all properties of a system at a given state. Thus, the system’s state changes to a completely distinct one if the value of even one property changes. When there is equilibrium in the system, no change in the value of properties occurs when isolated from its surroundings.
Types of Equilibrium
Phase equilibrium: It is a system of two-phase where the mass of each phase reaches equilibrium.
Chemical Thermodynamics helps in comprehending the combined effect of both heat and their state change. We will first explain chemical thermodynamics, with in-depth concept notes and explanatory video on the MSVgo app. MSVgo app has a video library that explains concepts with examples or explanatory visualizations or animation.
