Year 13 Kinetics

change in concentration of a reactant or product over time.

• rate of reaction
• limiting reactant
• excess reactant
• successful collision

reactant that limits how much product can be made

• limiting reactant
• rate of reaction
• excess reactant
• successful collision

reactant where there is more than enough to react with something else

• excess reactant
• rate of reaction
• limiting reactant
• successful collision

collisions between particles with sufficient energy to react.

• successful collision
• rate of reaction
• limiting reactant
• excess reactant

minimum amount of energy needed for a successful collision to occur

• activation energy

• surface area

the mass or moles of a substance in 1 dm3

• concentration
