How to tell reaction order from graph?

The easiest way to spot the reaction order of your enzyme is by looking at the graphs. All graphs show the activity of a reaction at different time points. The graphs can also show the concentration of the reactants and products. When you look at the graphs, you can quickly tell if the enzyme follows a first-order reaction or a zero-order reaction. First-order graphs have a linear reaction curve while zero-order graphs have a flat line.

How to tell reaction mechanism from rate vs. time curve?

Fortunately, the graphs we use to describe chemical reactions are often sufficient to determine the reaction mechanism. Graphs that show a sharp increase in reaction rate at a particular time point are strong evidence that a particular reaction pathway is occurring.

How to tell the order of reaction from a graph?

The order of reaction can also be determined by looking at a reaction graph. The point at which the initial steepest part of the graph begins is the beginning of the reaction, and the point where the reaction levels off is the end of the reaction.

How to find the order of reaction from a graph?

There are two ways you can look at a reaction graph: you can either look at the concentration of each species at each time point or you can look at the rate of change of each species at each time point. Using the rate of change method, you can find the order of reaction quite easily. This method involves looking at the steepest line on the graph and seeing where it intersects the other graphs. The point where the line and each curve intersect is the point at which the reaction rate is

How to tell reaction mechanism from rate equation?

When the reaction mechanism is stepwise, you can observe the change in the value of rate constant with increasing temperature. A sharp increase in reaction rate is a positive proof for a reaction step mechanism. A single sharp increase is a strong indicator of a reaction step mechanism. If you observe a smooth increase in the reaction rate, it could either be a reaction step or a smooth multi-step reaction.
