Chemical equilibrium occurs when the rate of the forward reaction is equal to the rate of the reverse reaction, resulting in no net change in the concentrations of reactants and products.
What are the factors that can affect chemical equilibrium?
Factors such as temperature, pressure, concentration, and the presence of catalysts can affect chemical equilibrium.
What is the principle of Le Chatelier?
Le Chatelier's principle states that if a system at equilibrium is subjected to a change, it will adjust itself to minimize the effect of that change and restore equilibrium.
What is the role of equilibrium constants in chemical equilibrium?
Equilibrium constants, such as Kc and Kp, are used to express the extent of the reaction at equilibrium and determine the concentrations or partial pressures of the reactants and products.
What are reversible and irreversible reactions?
Reversible reactions are those that can proceed in both the forward and reverse directions, while irreversible reactions only occur in one direction.
What is the significance of the equilibrium constant, K?
The equilibrium constant, K, provides information about the relative concentrations of reactants and products at equilibrium and helps predict the direction of the reaction.
How does temperature affect chemical equilibrium?
An increase in temperature generally favors the endothermic reaction, while a decrease in temperature favors the exothermic reaction.
What is the effect of pressure on chemical equilibrium?
For gaseous reactions, an increase in pressure shifts the equilibrium towards the side with fewer moles of gas, while a decrease in pressure shifts it towards the side with more moles of gas.
What is a homogeneous equilibrium?
A homogeneous equilibrium is one where all the reactants and products are present in the same phase.
What is a heterogeneous equilibrium?
A heterogeneous equilibrium is one where the reactants and products are present in different phases.
What is the role of a catalyst in chemical equilibrium?
A catalyst increases the rate of both the forward and reverse reactions equally, allowing the system to reach equilibrium faster.
How does concentration affect chemical equilibrium?
An increase in concentration of a reactant or product shifts the equilibrium in the direction that reduces the concentration, while a decrease in concentration shifts it in the direction that increases the concentration.
What is the difference between dynamic equilibrium and static equilibrium?
In dynamic equilibrium, the forward and reverse reactions continue at equal rates, whereas in static equilibrium, there is no movement or change.
Can equilibrium be altered by external factors?
Yes, external factors such as temperature, pressure, and concentration can alter the position of equilibrium by shifting it towards the reactants or products.
What is the concept of equilibrium position?
The equilibrium position refers to the relative concentrations of reactants and products at equilibrium, which may vary depending on the conditions of the reaction.
