FAQs on Fun Video: Calculating Equilibrium Concentrations Video Lecture - Chemistry for ACT

1. What is an equilibrium concentration?
Ans. An equilibrium concentration refers to the concentration of a chemical species when a reaction has reached a state of equilibrium. It is the concentration at which the rate of the forward reaction is equal to the rate of the reverse reaction.
2. How can equilibrium concentrations be calculated?
Ans. Equilibrium concentrations can be calculated using the initial concentrations and the stoichiometry of the reaction. The concentrations can be determined using an ICE (Initial, Change, Equilibrium) table and solving the equilibrium expression using the given equilibrium constant.
3. What is the purpose of calculating equilibrium concentrations?
Ans. Calculating equilibrium concentrations allows us to understand the composition of a system at equilibrium. It helps in determining the relative amounts of reactants and products present and provides information about the extent of the reaction.
4. What factors can affect the equilibrium concentrations of a reaction?
Ans. Factors such as changes in temperature, pressure, and concentrations of reactants or products can affect the equilibrium concentrations of a reaction. Le Chatelier's principle states that a system at equilibrium will shift to counteract any changes imposed on it.
5. Can equilibrium concentrations be altered by adding a catalyst?
Ans. No, adding a catalyst does not alter the equilibrium concentrations of a reaction. A catalyst speeds up the rate of the forward and reverse reactions equally, allowing the system to reach equilibrium more quickly but not affecting the final concentrations of the species involved.
