Chemical Equilibrium
General Chemistry • 8 topics in this chapter.
This Chemical Equilibrium chapter in General Chemistry focuses on reversible reactions and how reaction conditions determine the equilibrium position, with interactive calculators and explanations for equilibrium constants Kc and Kp, reaction quotients Q, and writing correct equilibrium expressions from balanced equations. It also supports Le Châtelier’s principle so you can predict how changes in concentration, pressure/volume, and temperature shift equilibrium and affect yields.
On this page you can compute K from equilibrium concentrations or partial pressures, compare Q vs K to predict the direction of change, and solve ICE-table style problems to find equilibrium concentrations for simple and more challenging systems. Step-by-step outputs help you set up the algebra correctly, track units and exponents, and understand when approximations are reasonable, which is especially useful for AP/IB and introductory college equilibrium problem sets.
The difficulty level ranges from beginner-friendly K and Q practice to advanced equilibrium calculations, making it valuable for high school, AP/IB Chemistry, and first-year university chemistry. Teachers can use it to demonstrate equilibrium reasoning clearly, self-learners can practice systematically until the workflow feels natural, and advanced users can quickly verify equilibrium expressions, calculated concentrations, and shift predictions for labs, exams, and deeper thermodynamics connections.
