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.
For an exothermic reaction at equilibrium, increasing the temperature will shift the equilibrium position to favor the reactants, as the system attempts to absorb the added heat. According to Le Chatelier's principle, this shift results in a decrease in the equilibrium constant (Keq). Therefore, as the temperature rises, Keq for the exothermic reaction decreases.
The equilibrium constant (Keq) reflects the ratio of concentrations of products to reactants at equilibrium in a chemical reaction. While Keq itself does not directly affect diffusion, it influences the concentration gradients that drive diffusion. When a reaction reaches equilibrium, the concentrations stabilize, impacting the net movement of molecules. Thus, changes in Keq can indirectly affect the diffusion rates by altering the concentration differences across a membrane or barrier.
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.
The substances left out from the equilibrium constant expression (Keq) are usually pure solids, pure liquids, and solvents. These do not affect the equilibrium position because their concentrations remain constant. Only species that are present in aqueous or gaseous form and participate in the reaction are included in the Keq expression.

Products. keq equals [products] / [reactants] . A (-) Keq indicates a reactant favored 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.

To determine the equilibrium constant (Keq) from the change in Gibbs free energy (G), you can use the equation: G -RT ln(Keq), where R is the gas constant and T is the temperature in Kelvin. By rearranging this equation, you can solve for Keq as Keq e(-G/RT).

The relationship between the standard free energy change (G) and the equilibrium constant (Keq) in a chemical reaction is that they 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 G and Keq are inversely related - as Keq increases, G decreases, and vice versa.
The relationship between the Delta G equation and the equilibrium constant (Keq) is that they are related through the equation: G -RT ln(Keq). This equation shows how the change in Gibbs free energy (G) is related to the equilibrium constant (Keq) at a given temperature (T) and the gas constant (R).
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.
