## order of reaction equations

$\frac{d[R]}{dt}=-k[R]; \ln [R]=-kt + \ln [R]_{0}; t_{\frac{1}{2}}=\frac{0.693}{k}$

### order of reaction equations

Do we need to know how to show to get from the derived rate law to the integral rate law or can we just know one or the other?

In order to understand the integrated rate law it is important to know where it came from, but I doubt Dr. Lavelle would ask us to specifically derive one equation from the other. If anything, developing an understanding of the relationship fosters a clearer understanding of reaction kinetics, though!

I think we should be ready for anything. We've spent a lot of time in class on derivations and integrations, so I wouldn't be surprised if he asks us to derive something at some point. It shows a true understanding of the material, and is something that could only be helpful to know!

You will need to know both which are on your equations sheet, but I highly doubt he would ask you to derive the integrated rate law.

I don't think you will be asked derive the integrated rate law.

Although Dr. Lavelle does a lot of derivations in class, I believe he does them so we can see the correlations. I doubt we would be asked to derive the integrated rate law since practical application seems to be more the theme of his exams

I do not believe that we will need to know the derivations. I would only think that we would need to if it is explicitly stated on the outline sheets.
