Rates
increase surface area
increases rate
increase temperature
increases rate
increases kinetic energy
increases chance of high energy collision between reactant particles
decrease volume
increases rate
increase reactant
increases rate
catalyst
increases rate
successful reaction
orientate particles
lower activation energy
less energy needed
collision theory
successful reaction
enough energy
correct orientation
Law of Conservation of Mass
mass
not created
not destroyed
mass before = mass after
