## Rate laws

$aR \to bP, Rate = -\frac{1}{a} \frac{d[R]}{dt} = \frac{1}{b}\frac{d[P]}{dt}$

### Rate laws

Will we ever need to assume the order of a reaction? Are we always going to be told if a reaction is in the zero, first, or second order?

Im not sure if we have to assume but we might have to infer if we were given the graph vs tome or something like that. Or a set of experimental data.

Well, we could possibly be asked to calculate the order of the reaction with respect to a certain substance given a table of concentrations.

We could also be given a graph and be asked whether reaction is zero order, first order, or second order to a particular reactant. For example, if the concentration decreases exponentially over time with respect to a particular reactant, then the reaction is second order to that reactant.

I think graphs will be given or the correlation will be explained.
