## Graphs

$\frac{d[R]}{dt}=-k[R]; \ln [R]=-kt + \ln [R]_{0}; t_{\frac{1}{2}}=\frac{0.693}{k}$

### Graphs

Why does the graph of time versus concentration need to be linear?

### Re: Graphs

I think the concentration is decreasing at a certain rate (with a certain slope) based on the reaction's k constant over time.

### Re: Graphs

The linear graphs help to determine what order a reaction is. It is linear because the k is a constant and it is the slope.
