What are the four factors that affect reaction rates? |
Temperature - as the temperature increases the speed of the molecules increase so they are moving faster and breaking more bonds. Concentration - the more molecules packed into a smaller space the greater the number of collisions. Surface area - amount of area of a piece of matter that we can see and is able to react. Catalyst - a substance that increases rate of reaction but is not a reactant. |
