### Number of steps to reach the overall reaction

Will the number of steps used in order to find the overall reaction equal the number of reactants? Are there any exceptions?

yes since each step is a reaction and all the steps together form the overall reaction, the number of steps is equal to the number of intermediate reactions

However, the number of steps will not always equal the number of reactants as the number of steps depends on the rate law. For instance, a reaction with two reactants can have the concentration of both reactants in the rate law, which would mean that both reactants occur in the rate-determining step, giving a single step mechanism. That is, two reactants will form the product in one step.

Yeah, I don't think it's always the case that the number of steps equals the number of reactants present. I am note sure however.
