Does someone have a good video explaining how to find a first order reaction vs a second?

If the reaction rate increases proportionally with the reactant concentration, then it's a first order reaction (assuming there's only 1 reactant) because the exponent is 1 in the rate equation. Rate = k[A]n
For example, if the reaction concentration doubles and the resulting reaction rate also doubles, then you know it's first order.

These videos explain reaction orders pretty well!

A first order reaction is characterized by the linear graph of concentration and time.
