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

### Differentiating Zero and One Order Reactions

Theoretically, since both the graphs of both zero and one would look similar(including the negative in the equation) how do we distinguish them?

You would look at the labels for the axes. For zero order, the straight line graph will be concentration vs time, but for first order it will be ln(concentration) vs time.

The 1st order reaction should look like an exponential decay function
