Rates Of Reaction Flashcards
factors effecting rate
Temperature, particle size, concentration, catalyst
how many factors are there
4
how to calculate average rate
change in quantity divide by time
what do u always add to the end of the rate
units
methods collecting gas
syringe and measuring cyclinder
you measure collected….
gas
what measurements can you use
volume, mass
the smaller the particle size the…….
faster the reaction
the lower the temperature the ….
slower the reaction
higher the concentration the….
faster the reaction
if a catalyt used then the reaction is….
faster
explain how increasing temperature increases rate of reaction
gives the particles more energy so they are faster and collide with more force so more likely to have successful collision
explain how increasing concentration increases rate of reaction
particles are more crowded so there is more of them so they are more likely to collide quicker and there are more particles to react with
explain how decreasing particle size increases rate of reaction
increasing surface area so there is more space to react with
rates of reaction can be explained by the…
collision theory
