FAQs on Integrated Rate Equation: Zero Order Reactions Video Lecture - Chemistry for JEE Main & Advanced

1. What is the integrated rate equation for a zero-order reaction?

Ans. The integrated rate equation for a zero-order reaction is given by the equation: [A] = [A]₀ - kt, where [A] is the concentration of reactant A at a given time, [A]₀ is the initial concentration of reactant A, k is the rate constant, and t is the time.

2. How do you determine the rate constant for a zero-order reaction?

Ans. The rate constant for a zero-order reaction can be determined by measuring the initial rate of the reaction at different concentrations of the reactant and plotting a graph of concentration versus time. The slope of the graph will be equal to -k, where k is the rate constant.

3. Can the rate constant for a zero-order reaction change over time?

Ans. No, the rate constant for a zero-order reaction remains constant throughout the reaction. This is because the rate of the reaction does not depend on the concentration of the reactant, but rather on the rate constant itself.

4. What happens to the concentration of a reactant in a zero-order reaction over time?

Ans. In a zero-order reaction, the concentration of the reactant decreases linearly over time. This means that the reactant is consumed at a constant rate, independent of its initial concentration.

5. How can the half-life of a zero-order reaction be calculated?

Ans. The half-life of a zero-order reaction can be calculated using the equation t₁/₂ = [A]₀ / (2k), where t₁/₂ is the half-life, [A]₀ is the initial concentration of the reactant, and k is the rate constant.
