FAQs on PYQs: Chemical Equilibrium Video Lecture - Physical Chemistry

1. What is chemical equilibrium?
Ans. Chemical equilibrium is a state in a chemical reaction where the rate of the forward reaction is equal to the rate of the reverse reaction. In other words, the concentrations of the reactants and products remain constant over time.
2. How is chemical equilibrium achieved?
Ans. Chemical equilibrium is achieved when the forward and reverse reactions occur at the same rate. This can be achieved by adjusting the reaction conditions such as temperature, pressure, and concentration of reactants and products. Once equilibrium is reached, the concentrations of reactants and products do not change, but the reactions continue to occur.
3. What factors affect chemical equilibrium?
Ans. Several factors can affect chemical equilibrium. These include changes in temperature, pressure, and concentration of reactants and products. Increasing the temperature generally favors the endothermic reaction, while decreasing the temperature favors the exothermic reaction. Increasing the pressure favors the reaction that results in a decrease in the number of moles of gas, while decreasing the pressure favors the reaction that results in an increase in the number of moles of gas. Changes in the concentration of reactants and products also affect equilibrium, with an increase in concentration shifting the equilibrium towards the opposite side.
4. How can Le Chatelier's principle be applied to chemical equilibrium?
Ans. Le Chatelier's principle states that when a system in equilibrium is subjected to a change in temperature, pressure, or concentration, it will respond by shifting the equilibrium to counteract the change. For example, if the concentration of a reactant is increased, the equilibrium will shift towards the products to use up the excess reactant. Similarly, if the temperature is increased, the equilibrium will shift in the endothermic direction to absorb the additional heat.
5. What are the implications of chemical equilibrium in industrial processes?
Ans. Chemical equilibrium is of great importance in industrial processes. Understanding and controlling equilibrium conditions allow industries to maximize the yield of desired products, minimize unwanted side reactions, and optimize the efficiency of chemical reactions. By manipulating factors such as temperature, pressure, and concentration, industries can achieve the desired equilibrium conditions to produce chemicals in an economically viable manner.
