straight line to fit data

[Alison Trinh 1E]

What does having a straight line when plotting data tell us?

[Helen Struble 2F]

Depending on the order of the reaction, you will have to plot time by a different y-axis to achieve a straight line with slope kr or -kr. For zero order reactions, simply plot [A] by t. For first order, plot ln[A] by t. For second order, plot 1/[A] by t. If you are given a graph of a straight line then, you can figure out the order by looking at the variable in thew y-axis.

[Sofia Barker 2C]

If you plot [A] vs time and get a straight line, this tells us that the reaction is zero order.
If you plot ln [A] vs time and get a straight line, this tells us that the reaction is first order.
If you plot 1/[A] vs time and get a straight line, this tells us that the reaction is second-order.

[Christine Honda 2I]

Depending on the order of the reaction, the straight line (whether it is a positive or negative slope and the graph axis labels itself) will tell you the order of the reaction.

[Emily Chirila 2E]

Given a graph of a straight line, you need to be able to know what order the reaction is based off the y-axis.

The slope will also give you a different constant value depending on the order of the reaction.
