What is an example of a first order rate reaction? Are there any types of reactions that we should generally know are likely to be first order ones?

The problem should always tell you the order of the reaction unless they want you to verify if it is first order or whatnot, in which case you would likely have to plot ln[A] by time and determine if the graph is a straight line. The decomposition of N2O5 to yield NO2 and O2 gas is a first order reaction, but I doubt you will have to memorize that.

Also as discussed in class, radioactive decay is a first-order reaction.

Unless experimental data is given to you with which you can find the reaction order, the reaction order will be given to you.
