What is the major factor that affects the rate of a hetrogeneous reaction ??????
The rates of all chemical reactions are affected by: concentration temperature molecular orientation particle size / surface area catalysts A “heterogeneous reaction” would imply that the reactants are not in the same phase, i.e. a solid and liquid or solid and gas or that there is a heterogeneous catalyst involved. All of the factors listed above are important to determining the rate of reaction whether it is heterogeneous or not. For instance, If one of the reactants was a solid then particle size and the resulting surface area might be an important factor given a constant concentration of the other reactant and temperature.
