FAQs on Chemical Equilibrium: Effects on Equilibrium & Le Chatelier's Video Lecture - Physical Chemistry for NEET

1. What is chemical equilibrium?
Ans. Chemical equilibrium refers to a state in a chemical reaction where the forward reaction rate is equal to the reverse reaction rate. In other words, the concentrations of reactants and products remain constant over time.
2. How does temperature affect chemical equilibrium?
Ans. Temperature plays a significant role in chemical equilibrium. According to Le Chatelier's principle, increasing the temperature of an exothermic reaction shifts the equilibrium towards the reactants, while increasing the temperature of an endothermic reaction shifts the equilibrium towards the products.
3. What happens to chemical equilibrium when pressure changes?
Ans. Changes in pressure can affect the equilibrium of a reaction. In general, increasing the pressure favors the reaction that produces fewer moles of gas, while decreasing the pressure favors the reaction that produces more moles of gas. This is based on Le Chatelier's principle.
4. How does the concentration of reactants and products impact chemical equilibrium?
Ans. The concentration of reactants and products directly affects chemical equilibrium. If the concentration of reactants is increased, the equilibrium will shift towards the products in order to consume the excess reactants. Conversely, if the concentration of products is increased, the equilibrium will shift towards the reactants to restore balance.
5. Can catalysts affect chemical equilibrium?
Ans. No, catalysts do not affect the position of chemical equilibrium. They speed up the forward and reverse reactions equally, allowing the system to reach equilibrium faster. However, the concentrations of reactants and products at equilibrium remain the same regardless of the presence of a catalyst.
