### Rate Order Graphs

What is the logic behind choosing the model with the most linear graph as the rate order?

look at what the x-axis and y-axis are and if its linear, its likely that order. For example, ln[A] vs. t if thats linear, its likely 1st order.
If you search on Google there are super helpful charts that break down 1st, 2nd, and zero order in terms of linear plot to determine the rate order and the exponential graphs that show concentration vs. time!

If you are only given the reactant concentrations and their respective times, you can use graphs to determine the order of each reactant. For example, if the graph of ln[A] vs. time is linear, it is first order. In addition, if [A] vs. time is linear, then it is zero order.

i find this diagram pretty helpful in determining order: (shows zero, first, and second order graphs respectively)
