rates of reaction Flashcards
what factors can affect the rate of reaction
temperature
particle size
concentration
catalyst
describe the relationship between concentration and the rate of reaction
higher concentration = faster reaction rate
the higher the concentration, the more particles there are to collide, the faster the reaction rate
describe the relationship between the temperature and the rate of reaction
higher temp = faster raection
the higher the temp, the faster particles will move so the more likley they are to collide
describe the relationship of particle size on the rate of reaction
the smaller the particle size = faster the reaction rate
smaller the particle size means more surface area for prticles to collide, faster reaction rate
describe the relationship between catalysts ans the rate of reaction
catalysts speed up the rate of reaction (remain unchanged and can be recovered)
how do you calculate the avergae rate of reaction
average rate = change in quantity
