In this section we will mathematically describe the concentrations of products and reactants for a system that has reached equilibrium in terms of an Equilibrium constant.

The reaction quotient can be used to predict the direction and extent of an equilibrium chemical reaction. At equilibrium, the reaction quotient (Q) is equal to the equilibrium constant (K) for the reaction, …

Nov 30, 2023 · Reaction Quotient vs. Equilibrium Constant: What's the Difference? The reaction quotient measures concentrations at any point in a reaction, whereas the equilibrium constant represents …

Going back to the beginning of this study guide, comparing Q and K can tell you if a reaction is in at the pre-equilibrium state, post-equilibrium state, or at equilibrium.

Q is the reaction quotient: the ratio of product/reactant concentrations (or partial pressures) at any point in the reaction. K is the equilibrium constant: the ratio of product/reactant concentrations when the …

This study guide covers the reaction quotient (Q), its calculation, and its relationship to the equilibrium constant (K). It explains how to use Q to predict the direction of equilibrium shifts.

While the equilibrium constant is determined at equilibrium and is temperature-dependent, the reaction quotient can be calculated at any point during the reaction and is not influenced by temperature.
