FAQs on Reversible Reactions and Equilibrium Video Lecture - Chemistry for GCSE/IGCSE - Year 11

1. What is a reversible reaction?
Ans. A reversible reaction is a chemical reaction that can proceed in both the forward and reverse directions. It means that the products of the reaction can react together to form the original reactants.
2. What is meant by equilibrium in a reversible reaction?
Ans. Equilibrium in a reversible reaction occurs when the rate of the forward reaction is equal to the rate of the reverse reaction. At this point, the concentrations of the reactants and products remain constant over time.
3. How does changing the temperature affect a reversible reaction?
Ans. Changing the temperature can shift the equilibrium of a reversible reaction. For an endothermic reaction, increasing the temperature will favor the forward reaction, while for an exothermic reaction, increasing the temperature will favor the reverse reaction.
4. What role does a catalyst play in a reversible reaction?
Ans. A catalyst is a substance that speeds up the rate of a reaction without being consumed in the process. In a reversible reaction, a catalyst can help both the forward and reverse reactions proceed faster, reaching equilibrium more quickly.
5. How does changing the concentration of reactants or products affect a reversible reaction at equilibrium?
Ans. Changing the concentration of reactants or products in a reversible reaction at equilibrium can disturb the equilibrium and shift it in the direction that minimizes the disturbance. This is known as Le Chatelier's Principle.
