Identify the limiting reactant in a chemical equation. Identify the excess reactant and calculate the amount remaining after the reaction is complete. Calculate the mass of a product when the amount of more than one reactant is given. Chemical reactions. A . chemical reaction . is when one or more substances change into different substances. . Example . iron + sulfur .  iron (ii) sulfide + energy. Go to textbook Page 225. Read page 225 and write definitions for the following into your notes.. . When the rates of the forward and reverse reactions become equal, the concentrations of the reactants and the products remain constant. This is the stage of chemical equilibrium. This equilibrium is . Part 1 – Kinetics. Part 2 – General Equilibrium. Kinetics: . the branch of chemistry that deals with the . rates. (how fast the reaction is) of chemical reactions .
