### Understanding n intuitively

Today in class, professor Lavelle went through how to understand that n would be 1 intuitively in an example from the course reader. In the course reader, it then proceeds how to get the number mathematically. I follow the math but I failed to understand how he knew the value of n before doing the math. Maybe I am missing a critical conceptual point that would lead to this conclusion. Can someone please explain how you would know what n is before doing the math for it? Thanks!

### Re: Understanding n intuitively

Just compare the concentration of one of the reactants, say [NH4+1] to the rate. After you've recognized that as the concentration doubles your rate doubles you can say that 2^n=2. Therefore, n must equal 1. This logic provides you with a shortcut.Hope this helps.
