WebAug 27, 2024 · It is a first order reaction. How do you graph a curved line? How can you tell if a graph is a first order reaction? To test if it the reaction is a first-order reaction, plot the natural logarithm of a reactant concentration versus … WebJan 26, 2015 · Nope, we are assuming it is a first order reaction because this reaction only has one step. And this step only has one reactant with a coefficient of 1. If this reaction has multiple steps, even if it has one reactant, the order of reaction may not … WebOct 28, 2024 · It gives two concentrations vs. time curves, and asks which reaction has the larger rate constant. The answer is (3) the reaction represented by the lower curve. I know that the reaction is first-order, hence r a t e = k [ A]. Thus, algebra reveals that [ … columbus blue jackets ticket sales
