User:Plop/Some equations

Here are some equations which are probably only useful to me.

"Easy" reaction rate formula

 * $$\mbox{reaction rate}={\mbox{change in mass or concentration}\over\mbox{time taken}}$$

Example


\begin{matrix} \mbox{reaction rate} & = & {\mbox{change in mass of magnesium}\over\mbox{time taken}} \\ & = & \frac{0.1}{10} \mbox{g magnesium used up per second} \\ & = & 0.01 \mbox{gs} ^{-1} \\ & \mbox{or} & 0.01 \frac{\mbox{g}}{\mbox{s}} \\ & \mbox{or} & 0.01 \mbox{ grams per second} \\ \end{matrix} $$
