FAQs on Integrated Rate Equation for First order Reactions Video Lecture - Chemistry for JEE Main & Advanced

1. What is the integrated rate equation for first-order reactions?
Ans. The integrated rate equation for a first-order reaction is given by the equation: ln[A]t = -kt + ln[A]0, where [A]t is the concentration of the reactant at time t, [A]0 is the initial concentration, k is the rate constant, and ln represents the natural logarithm.
2. How is the integrated rate equation derived for first-order reactions?
Ans. The integrated rate equation for first-order reactions can be derived by integrating the rate law expression for a first-order reaction. By integrating the differential rate equation, which is the derivative of the concentration with respect to time, we can obtain the integrated rate equation.
3. Can the integrated rate equation for first-order reactions be used to determine the reaction rate constant?
Ans. Yes, the integrated rate equation for first-order reactions can be used to determine the reaction rate constant. By plotting ln[A]t against time and obtaining a straight line, the slope of the line can be used to calculate the rate constant (k) of the reaction.
4. What is the significance of the slope in the integrated rate equation for first-order reactions?
Ans. The slope in the integrated rate equation for first-order reactions represents the negative rate constant (-k) of the reaction. It provides information about the rate at which the reactant concentration decreases over time.
5. Can the integrated rate equation be used for reactions other than first-order reactions?
Ans. No, the integrated rate equation discussed in this article is specific to first-order reactions. Reactions with different orders will have different integrated rate equations. The integrated rate equation for a reaction depends on the overall reaction order, which can be determined experimentally.
