How can you tell something is 2nd order?

When two first-order reactants affect the rate constant or when one second-order reactant

If you are given a plot of 1/[A] by time, and the curve is linear, then you know that the reaction is second order with respect to that reactant. The slope is equal to the rate constant.

It is second order if two first order reactants affect the rate constant

If the graph of 1/[A] vs time is linear, or if the exponents of the rate law add up to two, then the reaction is second order.

If you look at the units and liters and seconds are in the denominator then it is second order.

When the rate is affected by the concentration of two first-order reactants, it is a second order reaction.
