## Graphs

$\frac{d[R]}{dt}=-k; [R]=-kt + [R]_{0}; t_{\frac{1}{2}}=\frac{[R]_{0}}{2k}$

### Graphs

Do we need to know what the graphs will look like for zero, first, and second order reactions?

### Re: Graphs

It is probably a good idea to know what these look like just because that knowledge could potentially help you figure out which order a reaction is. It is a useful way to test the order of a reaction.

Knowing the graphs can be helpful since the slope (ln[A] vs. T graph) can tell you the value of k for each order reaction. In addition, the graph can help you identify what order the reaction is.

### Re: Graphs

They're definitely really helpful because they can tell you what order the reaction is simply based on what is being measured vs time. Then you can go from there and calculate the rate constant from the slope of the line.

### Re: Graphs

Can anyone post the graphs for each rxn and sort of explain them? I didn't really get them down in my notes in class

It’s good to know, just because some questions can be quirky like that. They’re pretty easy to learn since only one of them differs and all you need to know is the value on the y-axis of each order reaction.

### Re: Graphs

here are the graphs for zero order, first order, and second order, respectively
