Reaction Rate Effects ,[object Object],[object Object]
Concentration ,[object Object],[object Object],[object Object],There are less red particles in the same volume so there is less chance of a collision There are more red particles in the same volume so there is more chance of a collision so the reaction goes faster
Reaction Rate Effects ,[object Object],[object Object],[object Object],[object Object]
Surface area ,[object Object],[object Object],The particles on the surface can react When cut into smaller pieces there are more particles on the outside that can react
Reaction Rate Effects ,[object Object],[object Object]
Measuring rate of reaction Two common ways: 1) Measure how fast the products are formed 2)  Measure how fast the reactants are used up
