Kinetics - study of rates of reactions and how they are influenced by certain factors like concentration, temperature, catalysts, and surface area. Catalyst - substance that increases the rate of a chemical reaction without being consumed in the overall reaction. Reaction Rate - Increasing the surface area of the particles of solid reactants (by grinding the solid to a fine powder) causes an increase in the rate of reaction since solids react only at their surfaces
