Flashcards in Reaction Rates and Equilibria Deck (5)
What is Rate of Reaction
Change in concentration
How does Concentration affect the rate of a chemical reaction.
There are more molecules per unit volume so are more likely to collide successfully.
How does Temperature affect the rate of a chemical reaction.
Molecules have more kinetic energy so there are more frequent collisions and more effective collisions as they have sufficient energy.
How does Catalyst affect the rate of a chemical reaction.
Lowers the activation energy so more molecules have sufficient energy to have an effective collision and react.
