Is it true that a change in pressure may affect the equilibrium position but has no effect on the equilibrium constant?
Yes, a change in pressure may affect the equilibrium position by shifting the reaction towards the side with more moles of gas to relieve the pressure change, but it has no effect on the equilibrium constant because the equilibrium constant is determined solely by the reaction's intrinsic properties.
What is the difference between dissociation constant and equilibrium constant?
The dissociation constant describes the extent to which a compound breaks apart into its ions in a solution, specifically for weak acids or bases. The equilibrium constant, on the other hand, describes the ratio of product concentrations to reactant concentrations at equilibrium for a chemical reaction.
What would happen to a system at equilibrium if the temperature changed?
If the temperature of a system at equilibrium changed, the equilibrium position would shift to counteract the change. If the temperature increased, the equilibrium would shift in the endothermic direction to absorb the excess heat. If the temperature decreased, the equilibrium would shift in the exothermic direction to release more heat.
How do enzymes affect the equilibrium constant of a reaction?
Enzymes do not affect the equilibrium constant of a reaction. They only speed up the rate at which the reaction reaches equilibrium, but do not change the position of the equilibrium itself.
How can one determine the equilibrium constant from the change in Gibbs free energy (G)?
To determine the equilibrium constant from the change in Gibbs free energy (G), you can use the equation G -RT ln(K), where G is the change in Gibbs free energy, R is the gas constant, T is the temperature in Kelvin, ln is the natural logarithm, and K is the equilibrium constant. By rearranging this equation, you can solve for K to find the equilibrium constant.

What factors doesn't change the equilibrium constant of a reaction?
The equilibrium constant of a reaction is unaffected by changes in concentration, pressure, or volume, as these do not alter the intrinsic properties of the reaction at a given temperature. Additionally, the equilibrium constant remains constant regardless of the presence of catalysts, which only speed up the rate at which equilibrium is reached but do not change the position of equilibrium itself. However, the equilibrium constant is temperature-dependent; a change in temperature will alter its value.
What would happen to a system at equilibrium if the temperature changed?
If the temperature of a system at equilibrium changed, the equilibrium position would shift to counteract the change. If the temperature increased, the equilibrium would shift in the endothermic direction to absorb the excess heat. If the temperature decreased, the equilibrium would shift in the exothermic direction to release more heat.
If a liquid is sealed in a container and kept at constant temperature how does its vapor pressure change over time?
If a liquid is sealed in a container and kept at a constant temperature, its vapor pressure will initially increase until it reaches a constant value, known as the equilibrium vapor pressure. At this point, the rate of evaporation of the liquid equals the rate of condensation of the vapor, resulting in no further change in vapor pressure over time. This equilibrium is maintained as long as the temperature remains constant and the container remains sealed.
Factor that can change equilibrium constant?
Temperature
Does taking water out of an equilibrium reaction change the equilibrium constant?
No, the equilibrium constant is independent of concentration as long as the ratio of products and reactants remains as is. It can be effected by anything that would influence the ratio of products and reactants, such as changes in temperature or the addition of a catalysis.
Is the equilibrium constant for the forward reaction equal to the equilibrium constant for the reverse reaction?
No, the equilibrium constant for the forward reaction is not equal to the equilibrium constant for the reverse reaction. Instead, they are inversely related. If ( K_f ) is the equilibrium constant for the forward reaction, then the equilibrium constant for the reverse reaction ( K_r ) is given by ( K_r = \frac{1}{K_f} ). This relationship reflects the change in the direction of the reaction.
How do enzymes affect the equilibrium constant of a reaction?
Enzymes do not affect the equilibrium constant of a reaction. They only speed up the rate at which the reaction reaches equilibrium, but do not change the position of the equilibrium itself.
What is the temperature at which a liquid and gaseous phases are in equilibrium?
The temperature at which a liquid and gas are in equilibrium is called the boiling point. At this temperature, the vapor pressure of the liquid equals the atmospheric pressure, allowing the liquid to change into gas and vice versa at a constant rate.
