FAQs on Question Bank: Equilibrium - Chemistry Class 11 - NEET

1. What is the definition of equilibrium in a chemical reaction?
Ans. Equilibrium in a chemical reaction refers to the state where the rate of the forward reaction equals the rate of the reverse reaction, resulting in constant concentrations of reactants and products over time.
2. How can we determine the position of equilibrium in a reaction?
Ans. The position of equilibrium can be determined using the equilibrium constant (K). It is calculated by taking the concentration of products raised to the power of their coefficients divided by the concentration of reactants raised to the power of their coefficients at equilibrium.
3. What factors can affect the equilibrium position of a reaction?
Ans. The equilibrium position can be affected by changes in concentration, temperature, and pressure. According to Le Chatelier's principle, if an external change is applied to a system at equilibrium, the system will adjust to counteract the change.
4. What is Le Chatelier's principle?
Ans. Le Chatelier's principle states that if an external change (such as concentration, temperature, or pressure) is applied to a system at equilibrium, the system will shift in a direction that counteracts the change, thus restoring a new equilibrium.
5. How does temperature affect the equilibrium constant of a reaction?
Ans. The equilibrium constant (K) is temperature-dependent. For exothermic reactions, increasing the temperature will decrease K, while for endothermic reactions, increasing the temperature will increase K. This is because temperature changes affect the relative rates of the forward and reverse reactions.
