I understand the process in which we find the value of n, but I don't fully understand how we determine which experiment should be divided by another. For example, the in-class example had us dividing rate 2 by rate 1, but what if we divided rate 1 by rate 2. We would no longer get 2 as an answer and instead get 1/2. So how do you know which rate to divide by in order to get the right answer?
When solving for the reaction order, you want to try and divide the experiments as to end up with a whole number. However, ending up with fractions wouldn't necessarily make the problem wrong.
Trying to keep it in terms of ratios can help to figure out the exponent values easier. If we need to reduce the coefficients a bit in order to do so can help as well, but in essence nothing should specifically change.
