Important Topics From Chemical Thermodynamics for JEE Main Practice Paper

It will be easy for you to work out the JEE Main Practice Paper if you have a strong understanding of the Chemical Thermodynamics. You have to focus more on the important topics to answer most of the questions from the JEE Main Practice Paper on Chemical Thermodynamics. Here are some of the important topics of Chemical Thermodynamics.

  • Gibbs Free Energy:

Gibbs free energy is a crucial topic in chemical thermodynamics that helps predict whether a reaction is spontaneous or not. It considers both enthalpy and entropy changes, providing insights into a reaction's feasibility under specific conditions.

  • Enthalpy and Entropy:

Enthalpy measures the heat energy absorbed or released in a reaction, while entropy represents the degree of disorder in a system. Understanding their interplay is essential for assessing the spontaneity and direction of chemical processes.

  • Hess's Law:

Hess's Law is a fundamental concept that states the total enthalpy change of a reaction is independent of the reaction pathway. It's used to calculate enthalpy changes for complex reactions by summing up simpler reactions.

  • Heat Capacity:

Heat capacity quantifies the amount of heat needed to raise the temperature of a substance. Specific heat capacity, in particular, helps determine how materials respond to temperature changes, which is vital in thermodynamics and calorimetry.

  • Thermodynamic Equilibrium:

Thermodynamic equilibrium signifies a state in which no net change occurs in a system's properties. Understanding the conditions for achieving and maintaining equilibrium is essential for analyzing chemical reactions and phase transitions.

Equations To Score More in Practice Paper of JEE Main Chemical Thermodynamics

Equations are the base for solving the JEE Main Practice Paper. You have to know which equation or formula to use while solving the Practice Paper for JEE Main. Find the important equations you need to learn while working out the Practice Paper of JEE Main Chemical Thermodynamics.

1. First Law of Thermodynamics (Internal Energy Change):

\[\Delta U = q + w\]

2. Enthalpy Change:
