6. 2 Reaction Rates
Rate of Reaction Rate of reaction: the _______ speed that reactants turn into products
In order for reactants to occur, reactant particles must collide with each other with enough energy the hits • collision: __________ • increase collisions = _______ increase in reaction rate
Temperature • Temperature: ________ average energy of particles high temperature high energy faster _____ particles more and bigger collisions increase _____ reaction rate
Concentration
Concentration Solution: a ________ mixture of two or more substances Solvent: the _____ bigger part of the solution Solute: the _____ smaller part of the solution
Concentration amount Concentration: the ______ of solute dissolved in solution Concentrated solution: a solution with a _____ concentration (large amount of solute) higher Dilute solution: a solution with a _____ concentration (small amount of solute) lower
water + Cu. SO 4 solvent solute dilute concentrated
Concentration high concentration more ______ particles more ______ collisions low concentration (dilute) higher chance of ______ success high concentration higher reaction rate
Surface Area Surface area: the amount of area exposed to the outside low surface area high surface area
Surface Area high surface area more area for collision more collisions higher chance of success higher reaction rate
Catalyst: a substance that will speed up a reaction ________________ without being used up in the reaction A + B + catalyst → AB + catalyst
Example: Our bodies use enzymes to speed up reactions. Enzymes are molecules that help reactants combine together.
toxic Example: Cars use catalytic converters to break down ______ gases from __________. These toxic gases include carbon monoxide (CO), nitrogen oxides (NO, NO 2) and hydrocarbons. Nitrogen oxides: ______________________ Hydrocarbons: creates ______ Catalytic converters use platinum (Pt) and rhodium (Rh) and palladium (Pd) as catalysts. They are coated inside very small hollow tubes (high surface area!) where the toxic gases will travel through. combustion non-metal oxide (acid rain)
Cx. H y NO 2 CO NO
