Study Notes
Equilibrium Constant and Temperature
- An increase in temperature decreases the equilibrium constant for an exothermic reaction.
- An increase in temperature increases the equilibrium constant for an endothermic reaction.
Factors Affecting the Equilibrium Constant
- The value of the equilibrium constant for a reaction at a given temperature is not affected by the concentration of reactants or products.
Equilibrium Constant and Chemical Reactions
- The equilibrium constant measures the ratio of the concentrations of products to reactants at equilibrium for a chemical reaction.
- The equilibrium constant indicates the extent to which a reaction will proceed towards the products or reactants at a given temperature.
- If the equilibrium constant is much greater than 1, it indicates that the reaction strongly favors the products at a given temperature.
Pressure and Equilibrium Constant
- A change in pressure does not affect the equilibrium constant for a reaction at a given temperature.
Statement about Equilibrium Constant
- The equilibrium constant is a constant value for a reaction at a given temperature, and it does not change with the addition or removal of reactants or products.
Concentration of Reactants and Equilibrium Constant
- Increasing the concentration of a reactant does not affect the equilibrium constant.
