WebSo the concentration of my A versus time. If I graph that, and I end up with a straight line for this, then it would be first order reaction. Then for a second order reaction, if I graph the inverse of the concentration A, so basically 1 over the concentration A versus time. I graph that, and I end up with a straight line with a positive slope. WebTherefore, if we were to graph the natural logarithm of the concentration of a reactant (ln) versus time, a reaction that has a first-order rate law will yield a straight line, while a reaction with any other order will not yield a straight line (Figure 17.7 “Concentration vs. Time, First-Order Reaction”).
