Factors affecting rates of reaction thanks to michelle craig manitoba curriculum chemistry grade 12 kinetics, topic 3-08 objectives to design short experiments to investigate and explain qualitatively using collision theory the relationship between reaction rate and temperature, concentration, catalyst, and surface area.
Rates of reaction different speeds of and there will be higher chance of effective collisions, thus increasing the rate of reaction some info and examples are from past papers, booklets my teacher made (i thank and credit his hard work) and textbooks about me. Chemical reactions are the heart of chemistry even the position of the reactants will affect the reaction rate they cannot make impossible reactions occur, they only contribute to the reaction to increase the reaction rate. Rates of reaction the rate of a reaction can be measured by the rate at which a reactant is used up, or the rate at which a product is formed the temperature, concentration, pressure of reacting gases, surface area of reacting solids, and the use of catalysts, are all factors which affect the rate of a reaction.
