## deriving the integrated rate laws

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

### deriving the integrated rate laws

Are we expected to know how to derive the integrated rate laws for the final? Or are we just need to know how to use them?

### Re: deriving the integrated rate laws

I dont expect there to be a question which explicitly asks us to derive a particular rate law, but knowing their derivations may be useful for more applied questions during which you may forget a particular formula. At that point, you could simply derive it and not miss unnecessary points :)

### Re: deriving the integrated rate laws

Also wanted to note that the rate laws on the constants and equation sheet will not be labeled which order it is for. So I would recommend getting familiar with the different formulas for zero, first and second order formulas and how to use them. As Saman has sated it may be helpful to know how to derive it yourself but its not mandatory to do it since the derivations will be on the formula sheet. I would go over homework questions so you can understand when to use what question and what information will be needed and etc.
