### Calculating the Rate Constant for a First-Order ReactionTo determine the rate constant for a first-order reaction from a graph, you can use the following methodology:#### Instructions1. **Graph Plotting**: - Plot the natural logarithm of the concentration of reactant \([A]\) against time \(t\). - The y-axis will represent \(\ln [A]\), and the x-axis will represent time \(t\).2. **Graph Analysis**: - The graph of \(\ln [A]\) versus time will yield a straight line if the reaction is first-order.#### Matching Concepts to Graph Analysis**Fill-in-the-Blank Question:**- **Sentence**: "On the graph of \(\ln[\text{A}]\) versus time, the rate constant, \_\_\_\_, is the \_\_\_\_ of the straight line."**Options to Fill in the Blanks**: - positive slope - negative slope - y-intercept - \(t\) - \(A\) - \(\ln[A]_t\) - \(k\)**Correct Answers**: - First Blank: \(k\) - Second Blank: negative slope**Completed Sentence**: "On the graph of \(\ln[\text{A}]\) versus time, the rate constant, \(k\), is the negative slope of the straight line."#### Practical Example:Consider you have graph data where:- The y-axis (vertical) shows \(\ln [A]\).- The x-axis (horizontal) shows time \(t\).Plot the data points, draw the best-fit straight line through these points, and determine the slope of the line. The negative of this slope equals the rate constant \(k\) for the first-order reaction.#### ConclusionUnderstanding how to extract the rate constant from a graphical analysis is crucial in chemical kinetics. This method allows for an accurate determination of reaction rates and understanding of reaction mechanisms.
