Graph of first and zero order reactions

Postby Angela_Park_1F » Tue Feb 28, 2017 12:04 am

Hi, Looking at the tangent graphs of the first order and zero order reactions, we see that both slopes are -k. So it looks like a straight line going down. Would we be able to tell if it is a first or zero order reaction just by looking at the graphs? If not, what other information do we need?

The rate law should be the indication.

You could tell if the graph is a first order reaction or a zero order reaction by looking at what the x and y axes represent.
For example
First order- y axis is ln [a] and x axis is time
Zero order-y axis is A and x axis is time
