In this lesson, we will learn how to plot concentration–time data for first-order reactions to calculate the rate constants and initial concentrations.
Q1:
The concentration of a reactant A was monitored during the course of a reaction. The data were plotted on a graph of lnA[] against time. If the reaction is first order with respect to A, what is the initial concentration of A in terms of the gradient of the plot š and the š¦-intercept š?
Q2:
The concentration of a reactant A was monitored during the course of a reaction. The data were plotted on a graph of lnA[] against time. If the reaction is first order with respect to A, what is the rate constant of the reaction in terms of the gradient of the plot š and the š¦-intercept š?
Q3:
Compounds A and B react according to the following equation: A+BC The reaction is first order with respect to A, and B is in large excess. Which function of the reaction rate š varies linearly with the reaction time?
