Besides the four main factors that effect rate of reaction (surface area, concentration, temperature and the use of a catalyst), do mass [of a substance such as marble chips] or volume [of an acid such as hydrochloric acid] effect rate of reaction, and if so why? If not, why also?

Rate of reaction is number of reactions per given time period. Neither does the mass or the volume of the given acid/base affect the rate of reaction.

The size of the marble chips (surface area) and concentration of hydrochloric acid would both have an influence on the rate of the reaction. If the marble chips are the same size and the concentration of acid used is constant, then neither would increase by adding mass of chips or volume of acid.

The others are partially correct. Keep in mind, however, that the concentration of the acid will decrease as the reaction continues, thus deceasing the rate.

the mass of substance counts too, because the rate of reaction will proceed according to how much mass of substance is present.
