Rate Of Reactio

Question 1

Particle size

Answer 1

Smaller particle size means larger total surface area
Higher frequency of EFFECTIVE collision

Question 2

Temperature

Answer 2

Higher temperature has more kinetic energy
Higher frequency of EFFECTIVE collision
Rate of reaction increases

Question 3

Concentration

Answer 3

Higher concentration means more reactant particles PER UNIT VOLUME
Higher frequency of effective collision
Rate of reaction increases

Question 4

Pressure

Answer 4

(GAS ONLY)
Higher pressure means more reactant particles PER UNIT VOLUME
Higher frequency of effective collision
Rate of reaction increases
