Final answer:
The factors that affect the rate of a closed reaction include concentration of reactants, surface area, and temperature.
Step-by-step explanation:
The factors that affect the rate of a closed reaction include:
- Concentration of reactants: Increasing the concentration of reactants generally increases the reaction rate. This is because a higher concentration provides more reactant molecules, increasing the chances of successful collisions between them.
- Surface area: Increasing the surface area of the reactants also increases the reaction rate. This is because a larger surface area allows for more contact between reactant molecules.
- Temperature: Increasing the temperature generally increases the reaction rate. This is because higher temperatures provide the reactant molecules with more kinetic energy, leading to more frequent and energetic collisions.
