Factors that affect rate of reaction

• Concentration - higher concentration of reactants usually increases the rate because there are more particles available to collide
• Temperature- increased the temperature gives particles more energy which makes them move faster and collide more often speeding up the reaction
• Surface area - if a solid reactant is broken into smaller pieces it has a larger surface area fro collision which can increase the rate
• Catalyst - these substance that speed up a reaction without being consumed in the process they lower the activation energy needed for the reaction to occur
• Catalyst - these substance that speed up a reaction without being consumed in the process they lower the activation energy needed for the reaction to occur
• Pressure - for reaction Involving gases increase the presure can increase the rate by reducing the volume and forcing the gas molecules closer together
