Standard Enthalpy Changes – Chemistry Class 11 Chapter 6.3 | Chemical Energetics new syllabus 2025

This PowerPoint presentation explains the concept of standard enthalpy changes from Chapter 6.3 of Chemistry-XI (1st Year). It covers key topics including:

Definition and conditions for standard enthalpy changes

Enthalpy change of reaction (ΔHr)

Enthalpy of combustion (ΔHºC)

Enthalpy of formation (ΔHºf)

Atomization (ΔH°at)

Neutralization (ΔH°n)

Electron affinity (ΔH°ea)

Practice questions and examples

This presentation is ideal for teachers, students, and self-learners preparing for board exams or improving their understanding of chemical energetics.
