Today’s Agenda…Finish notes & discussion from yesterdayEdit multiple choiceNew multiple choice questions about chemical reactionsIntroduction to Reaction Rate

Reaction Rate

Study Pack #5

Chemical ReactionsWhen the particles in your reactants bump into each other a chemical reaction can occurThink about when baking soda particles bump into vinegar particles!

Chemical ReactionsIf we can get more particles to bump into each other more often, we can speed up a chemical reaction!

Reaction RateA reaction rate is the speed at which a reaction occursChemical reactions do not all occur at the same rateSome happen faster and some slowerExample: Compare the chemical reaction in a match to that of spoiling foodHow fast a reaction happens depends on how easily the particles can get together to make a reaction occur

Reaction RateIf a reaction has a low rate, that means the particles get together and react at slower speeds than a reaction with a high rateThe reaction rate depends on what types of particles are reacting

Rates of Chemical Reactions

Reaction rate also depends on other factorsFactors that affect the rate of a chemical reaction are:ConcentrationSurface areaTemperature

Rates of Chemical Reaction

Concentration is how much of one substances is in a certain volume of anotherLet’s look at an example!

Exit SlipHow did concentration affect the reaction rate of the chemical reaction that you saw on the video? Justify your answer!
