Study Notes
Factors Affecting Reaction Rate
- Temperature affects the rate of a reaction by altering the frequency of collisions between reactant particles.
- An increase in surface area of a reactant leads to an increase in the rate of reaction because more reactant particles are exposed to collide.
Factors Unrelated to Reaction Rate
- The presence of light is least likely to affect the rate of a reaction involving light.
Reactant Nature and Reaction Rate
- The nature of the reactants affects the rate of a reaction primarily through the ease of bond-breaking and formation.
Concentration and Reaction Rate
- An increase in concentration of reactants leads to an increase in the rate of reaction, as more reactant particles are available to collide.
