Yes vinegar or acetic acid removing some will want the reaction to proceed left instead of right causing the reaction to slow C2H4O2 +NaOH Heating the vinegar up will make the reaction proceed faster, grinding up NaOH increases surface area allowing the reaction to move faster as well and the volume of the container doesn't make sense unless they specify what they did

Which statement best describes how a catalyst affects the reaction rate of a chemical reaction? The addition of a catalyst decreases equilibrium and slows down the reaction. The addition of a catalyst increases the temperature of the reactants and speeds up the reaction. The addition of a catalyst decreases the required activation energy and speeds up the reaction. The addition of a catalyst increases the potential energy of the reactants and slows the reaction.
