Identify the definition of reactants in a chemical reaction: Reactants are the starting substances that undergo change during the reaction.
Understand that reactants are consumed in the process of forming products, meaning they are used up as the reaction proceeds.
Differentiate between reactants and other components like catalysts, which speed up the reaction but are not consumed, and products, which are formed as a result of the reaction.
Recognize that reactants are typically listed on the left side of a chemical equation, indicating the substances present before the reaction occurs.
Conclude that in the context of the given options, reactants are 'The substances that are consumed during the reaction.'
