During lecture, Professor Lavelle mentioned how first order reactions produce straight line plots of ln[reactant] vs time with a slope that equals -k. However, he proceeded on with lecture and then mentioned how first order reactions produce exponential curves that are decreasing. Can someone explain the graph of first order reactions? Are they linear or decreasing curves?
The graph of ln[A] vs. time is linear for first order reactions, but the graph of [A] vs time is exponential decay, because e is applied to undo the ln. That is the difference between the two graphs but both of them are for first order reactions, the only difference is the two variables.
