## Multi-Reactant Concentration Changes

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

### Multi-Reactant Concentration Changes

In lecture last week it was said to plot [B] vs time, ln[B] vs time, and then 1/[B] vs time until you get a linear slope in order to determine the order of B. What if you get a straight line for more than one of these?

### Re: Multi-Reactant Concentration Changes

You won't get a straight line for more than one of these because each graph represents a different variation of [B] vs time. [B], ln[B] and 1/[B] all have different plots.
