Jan 10, 2023 · We can define a new quantity called the reaction quotient as a function of the partial pressures of each substance:\(^1)\) \[ Q_P = \dfrac{P_{\text{C}}^c \cdot P_{\text{D}}^d}{P_{\text{A}}^a \cdot P_{\text{B}}^b}, \label{10.1.5} \] and we can then simply rewrite Equation \ref{10.1.4} using Equation \ref{10.1.5} as:
Nov 13, 2022 · Define "the equilibrium state of a chemical reaction system". What is its practical significance? State the meaning and significance of the following terms: reversible reaction; quantitative reaction; kinetically inhibited reaction; Explain the meaning of the statement "equilibrium is macroscopically static, but microscopically dynamic".
Aug 14, 2020 · The reaction Quotient (\(Q\)) is used to determine whether a system is at equilibrium and if it is not, to predict the direction of reaction. The reaction Quotient (\(Q\) or \(Q_p\)) has the same form as the equilibrium constant expression, but it is derived from concentrations obtained at any time.
The reaction quotient meanwhile is taken at any instant of time and can have infinitely many possible values. The purpose of the reaction quotient is just to compare to the equilibrium constant to judge which reaction rate will be favored; the forward or the reverse. Hope that helps.

Derive reaction quotients from chemical equations representing homogeneous and heterogeneous reactions. Calculate values of reaction quotients and equilibrium constants, using concentrations and pressures. Relate the magnitude of an equilibrium constant to properties of the chemical system.
Note that the reaction quotient takes the exact same form as the equilibrium constant, and is a function of concentrations and/or activities of the reactants and products. The difference is that Q applies when the reaction is at non-equilibrium conditions, and therefore its value can vary.
