So our reactive x and the gas state reacts in a single step to produce two products, y and z, also in a gas state. Now, we already spoke about what the rate law was. The rate law of any reaction is a mathematical representation of the relationship between the concentration of the reactants and our rate of reaction. And we said that the general form is as follows rate of forward reaction is equal to the constant of our Ford reaction times the concentration of reactants to some power A. Now, this A represents the order of our reactants. And since the only reactant is the x reactant, this A represents the order of the entire reaction.
