## Zero order reactions

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

### Zero order reactions

I remember in class Dr. Lavelle mentioned that as the order of a reaction increases, the reaction becomes more rare. Does that mean then that zero order reactions are the most common?

I don’t think the professor ranked how common the first three orders were, just that they are the most common and that anything above a third order reaction became rarer and rarer.

I don't think the textbook or Lavelle ever talked about its commonality in terms of ranks. I tried doing a Google Search too, but that just came up empty, so I don't think it's a concern we need to really understand.

### Re: Zero order reactions

Zero order reactions are more common because the rates of these reactions are independent of the concentration of reactants. Increasing order reactions are less common because they require they require molecules to collide at specific moments in time. P

### Re: Zero order reactions

It would make sense that the 0 order reaction is most common because it takes place when concentration of reactants is very high.
