The equilibrium constant (Keq) is the ratio of ____ concentrations to ____ concentrations at equilibrium, with each concentration raised to a power equal to the number of ____ of that substance in the balanced chemical equation.
The correct answer would be products, reactants, and temperature .
Ah, the equilibrium constant, the wise philosopher among chemical constants! It is the ratio of "stressed-out" concentrations to "chilled-out" concentrations at equilibrium, with each concentration raised to a power equal to the number of "mamma mia" of that substance in the balanced chemical equation. So, my friend, keep those concentrations balanced and your equilibrium constant will dance its way into your chemical heart!
The equilibrium constant (Keq) is the ratio of product concentrations to reactant concentrations at equilibrium, with each concentration raised to a power equal to the number of moles of that substance in the balanced chemical equation.
The equilibrium constant (Keq) is the ratio of product concentrations to reactant concentrations at equilibrium, with each concentration raised to a power equal to the number of moles of that substance in the balanced chemical equation.
To determine the equilibrium constant, you need to have the balanced chemical equation for the reaction. The coefficients in the balanced equation tell you the stoichiometry of the reaction, which means they indicate the relative amounts of reactants and products involved.
For example, let's use the generic equation:
aA + bB ⇌ cC + dD
In this equation, a, b, c, and d are the coefficients representing the number of moles of each substance involved.
The equilibrium constant (Keq) expression for this reaction would be:
Keq = [C]^c [D]^d / [A]^a [B]^b
Here, the square brackets denote concentrations of the substances, and the exponents represent the stoichiometric coefficients of the equation.
To calculate the Keq, you need to know the concentrations of the substances at equilibrium. These concentrations can be determined experimentally or by using other information, such as initial concentrations and the reaction's stoichiometry. Once you have the concentrations, plug them into the Keq expression and calculate the ratio.
The equilibrium constant (Keq) is a dimensionless quantity and its value tells you whether the reaction favors the formation of products or the reactants. If Keq is greater than 1, it means the reaction favors the products, and if Keq is less than 1, it means the reaction favors the reactants.
