Limiting Reactant MDCAT Quiz is an important term in chemistry; it refers to the substance present in a chemical reaction that gets used up completely and, therefore, limits the formation of the amount of product that can be created. This topic is important for the MDCAT student because this directly influences stoichiometric calculations, reaction yields, and chemical process efficiency. Many questions in the MDCAT Quiz dealing with limiting reactants require the student to apply knowledge of molar ratios, knowledge of molar masses, and reaction completion. It is very necessary to master this subject in order to solve problems accurately and quickly in this exam.
