What three factors effect the rate of reaction A. Temperature, Surface Area and concentration 1 of 6 Chemistry C6 Rate of Reaction Q. How does surface area affect reaction speed and why. A. A greater surface area means the particles are more exposed and thus more likely to collide with other reactants. 2 of 6 Chemistry C6 Rate of Reaction Q. How does temperature affect rate of reaction and why. A. Higher temperatures supply the particles with more energy allowing them to move and collide more vigorously 3 of 6 Chemistry C6 Rate of Reaction Q. How does Concentration effect rate of reaction A. More particles in a smaller space means collisions are more likely thus increasing rate. 4 of 6 Chemistry C6 Rate of Reaction What are catalysts Catalysts accelerate reactions by supplying reactants with the energy needed to trigger a reaction without being used up themselves. 5 of 6 Chemistry C6 Rate of Reaction What are biological catalysts called A.Enzymes. 6 of 6
