Reaction quotient
The Reaction Quotient - Chemistry LibreTexts
The reaction quotient ( Q ) measures the relative amounts of products and reactants present during a reaction at a particular point in time.
a dimensionless quantity that provides a measurement of the relative amounts of products and reactants present in a reaction mixture
The reaction quotient Q (article) - Khan Academy
The reaction quotient Q is a measure of the relative amounts of products and reactants present in a reaction at a given time.
Introduction to reaction quotient Qc (video) - Khan Academy
Introduction to the reaction quotient Qc, and comparing the reaction quotient with the equilibrium constant to predict how concentrations will change.
Calculating the Reaction Quotient, Q
Q can be used to determine which direction a reaction will shift to reach equilibrium. If K > Q, a reaction will proceed forward, converting reactants into ...
15.2: Equilibrium Constant and Reaction Quotient
In this section we will mathematically describe the concentrations of products and reactants for a system that has reached equilibrium in terms of an ...

Using the reaction quotient | Equilibrium | AP Chemistry - YouTube
By comparing the reaction quotient to the equilibrium constant, we can predict the direction a reaction will proceed to reach equilibrium.
Using the reaction quotient (video) - Khan Academy
Video transcript. - [Instructor] The reaction quotient is symbolized by the capital letter Q. And it tells us whether a reaction is at equilibrium or not. If ...
Reaction Quotient — Definition & Overview - Expii
The reaction quotient is the ratio of the concentration of products to the concentration of the reactants. It is used to determine the direction of a ...
Equilibrium Constant & Reaction Quotient | Calculation & Examples
The equilibrium constant (K) is the product-to-reactant ratio in a reversible reaction at which there is no net change in the concentrations because the system ...
The Reaction Quotient | DP IB Chemistry: SL Revision Notes 2016
The reaction quotient expression is Reaction mixture 1: In this mixture Q >> K c , so Q has to decrease to reach K c . This means the reaction must be moving ...
Chemical Equilibria and Reaction Quotients - YouTube
Many chemical reactions don't just go one way, they go forwards and backwards. Once there is balance between the two, this is an equilibrium ...
4.2 – The Equilibrium Constant & Reaction Quotient
The equilibrium constant is equal to the rate constant for the forward reaction divided by the rate constant for the reverse reaction.
Writing equilibrium constant and reaction quotient expressions (video)
Pure solids and liquids are omitted from the expression since their concentrations are their density, and density does not change for a specific chemical. The ...
Reaction Quotient: Predicting Direction of a Reversible ... - JoVE
As the reaction proceeds toward equilibrium in the forward direction, reactant concentrations decrease (as does the denominator of Qc), product ...
