Please answer the following question: I have a new situation: Henry and Tiffany are performing chemical reactions in their high school chemistry class. Henry performs his reactions with the use of a catalyst. Tiffany performs the same reaction with no catalyst present. But I can use this background: A catalyst is a substance that increases the rate of a chemical reaction. A catalyst is a substance that increases the rate of a chemical reaction. The presence of a catalyst is one of several factors that influence the rate of chemical reactions. (Other factors include the temperature, concentration, and surface area of reactants.) A catalyst isn't a reactant in the chemical reaction it speeds up. As a result, it isn't changed or used up in the reaction, so it can go on to catalyze many more reactions. What is an answer for this question: Will Henry's catalyst be used up after it catalyzes some reactions, yes or no?
A:
no
