A catalyst's job is to reduce a reaction's activation energy. Here, the spark gives the reactant molecules the energy they need to reach the highest threshold level. The spark is not serving as a catalyst as a result.
A catalyst is a sort of chemical that can alter the reaction's course and alter the rate at which it occurs. It has the ability to dissolve or recreate the chemical connection that unites the atoms or molecules of various elements.
When the process is finished, the catalyst can regenerate because it only interacts with reactants to create intermediates and the finished product.
