Chemical Reactions and Products

The video tutorial explains how to write equilibrium constant expressions for various chemical reactions. It covers the concept of equilibrium constants, the ratio of product to reactant concentrations, and provides examples including reactions during a lightning storm, HCl with oxygen, acetic acid with ethanol, hydrogen fluoride decomposition, and nitrogen dioxide conversion. Each example demonstrates how to calculate the equilibrium constant (Kc) by raising the concentration of products and reactants to the power of their coefficients in the balanced equation.
