Feb 13, 2023 · To test if it the reaction is a first-order reaction, plot the natural logarithm of a reactant concentration versus time and see whether the graph is linear. If the graph is linear and has a …

To determine if the reaction is first-order, plot the natural logarithm of the concentration versus time and see whether the graph is linear. The reaction will be first-order if the graph is linear with a negative …

Jul 23, 2025 · When plotted on a graph, a first-order reaction yields a straight line when ln [A] is plotted against time. This graphical representation confirms the first-order nature of the reaction.

Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like...

For a first order reaction, as shown in the following figure, the plot of the logrithm of [A] versus time is a straight line with k = - slope of the line. Other graphs are curved for a first order reaction. For a …

Example of graphing first-order rate data to see a linear relationship, and calculating rate constant k from the slope.

For a first-order reaction, a plot of the natural logarithm of the concentration of a reactant versus time is a straight line with a slope of − k. For a second-order reaction, a plot of the inverse of the …

To gain an understanding of graphical methods used to determine rate laws. To gain an understanding of half-life with respect to first-order reactions.

For first-order reactions, the equation ln [A] = -kt + ln [A] 0 is similar to that of a straight line (y = mx + c) with slope -k. This line can be graphically plotted as follows. Thus, the graph for ln [A] v/s t for a first …

In first-order reactions, the rate of the reaction is directly/linearly proportional to the concentration of the reactant. This can be seen in the differential rate law which shows how the rate of a reaction …
