How does temperature affect the Keq of a reaction?
Changing the temperature will change Keq. (apex.)
What is the expression that represents the equilibrium constant expression for H2SO3?
H2SO3 will ionize to H+ + HSO3-. The Keq = [H+][HSO3-]/[H2SO3]HSO3- will ionize to H+ + SO3^2-. The Keq = [H+][SO^2-]/[HSO3-] ... very small value
What is the relationship between the equilibrium constant (Keq) and the standard Gibbs free energy change (G) in a chemical reaction?
The equilibrium constant (Keq) and the standard Gibbs free energy change (G) in a chemical reaction are related through the equation G -RT ln(Keq), where R is the gas constant and T is the temperature in Kelvin. This equation shows that the value of Keq is related to the spontaneity of a reaction, with a larger Keq indicating a more favorable reaction in terms of products forming over reactants.
What are the units for the equilibrium constant, Keq?
The units for the equilibrium constant, Keq, are dimensionless.
Does the equilibrium constant, Keq, have units?
No, the equilibrium constant, Keq, is a unitless quantity.
How does temperature affect the Keq of a reaction?

What stressors will affect the value for Keq according to Le Chatelier's principle?
Changes in temperature, pressure, and concentration of reactants or products can affect the equilibrium constant (Keq) value according to Le Chatelier's principle. Increasing temperature typically decreases Keq for an endothermic reaction and increases it for an exothermic reaction, while changes in pressure can affect Keq for reactions involving gases. Changes in concentration can shift the equilibrium in a way that either increases or decreases the Keq value.
What is keq for the reaction n2 3h2 2nh3 if the equilibrium concentrations are nh3 2 m n2 3 m and h2 1 m?
K(eq)= 1.33
What is the expression that represents the equilibrium constant expression for H2SO3?

How does the catalyst affect the Keq value of a reacti on?
A catalyst does not affect the value of the equilibrium constant (Keq) of a reaction. The presence of a catalyst increases the rate of both the forward and reverse reactions equally, allowing the system to reach equilibrium more quickly but does not change the final equilibrium composition.

If keq equals 740 What is favored starting material or product?
Products. keq equals [products] / [reactants] . A (-) Keq indicates a reactant favored reaction.
How does temperature affect Keq of a reaction?
Changing the temperature will change Keq - apex (Explanation): Keq is closely related to temperature and is part of the equation, so changing temperature will change Keq. Temperature does speed up the reaction sometimes, but that is not the only thing that it can affect.
What is the relationship between the equilibrium constant (Keq) equation and the standard Gibbs free energy change (G) in a chemical reaction?
The equilibrium constant (Keq) equation and the standard Gibbs free energy change (G) are related through the equation G -RT ln(Keq), where R is the gas constant and T is the temperature in Kelvin. This equation shows that the value of Keq determines the direction and extent of a chemical reaction, with a lower Keq indicating a reaction that favors the reactants and a higher Keq indicating a reaction that favors the products. The sign of G also indicates the direction of the reaction, with a negative G indicating a spontaneous reaction and a positive G indicating a non-spontaneous reaction.
What is the equilibrium constant for the reaction SO2 plus NO2--SO3 plus NO?
SO2(g) + NO2(g) ==> SO3(g) + NO(g)Keq = [SO3][NO]/[SO2][NO2] Without knowing concentrations, one cannot calculate the actual value of Keq.
