Graphs of first order reaction
WebConsidering a chemical reaction at two different temperatures T 1 and T 2, whose corresponding rate constants are k 1 and k 2 respectively, the logarithmic form of the Arrhenius equation is: ln k 1 = ln (A) – E a /RT … WebIf you graph the first order reaction. The first order reaction basically ends up with a straight line with a positive slope. Then that's not right, because it has to be a negative slope. So it will have to be either zero first for second order, assuming that it's either zero, first or second. It has to be only one of these three.

WebMar 8, 2024 · Therefore, a zero order reaction is usually graphed as [A] vs. time, which should be a straight line. If it isn't a straight line then it is not a zero order reaction. For first order reactions, the integrated rate law is ln [A] = -kt + ln [A]initial. In this case, a graph of ln [A] vs. time should create a straight line. Top. Silvino Jimenez 1A.
