### Equations

Will we have to know how to derive the zero-, first-, and second-order equations, along with the half-life equations on the final?

### Re: Equations

I feel that we just have to know what they are and when to use them although knowing how to derive them may end up being useful.

### Re: Equations

I doubt that he would ask us to derive the zero, first, second, and half life equations since they are given on the equation sheet. It probably wouldn't hurt to be able to go from the given rate laws to the integrated rate laws though.

### Re: Equations

While it could come up on the final, I don't think Dr. Lavelle has asked us in either 14A or 14B to derive any equations. I think they are provided on the formula sheet too.

### Re: Equations

We do not need to know how to, since the integrated rate laws will be provided on the formula sheet. However, according to my TA, it may be useful to memorize other helpful forms of these laws that do not appear on the formula sheet.

### Re: Equations

It is provided on your equation sheet but it is useful to know how to derive the half life ones since let's say you are asked to find the how much time it takes for the concentration to be 1/15 initial, you would first need to derive an equation for that (exactly the way you do for half life) then solve
