AP Chemistry / Unit 5: Kinetics
5.1 Reaction Rates
Notes
Rate = change in concentration over time. Rates increase with higher concentration, higher temperature, more surface area, and catalysts.
Practice
Powdered sugar dissolves faster than a cube because of:
More exposed particles.
For $2A\to B$, if $A$ is used up at 0.2 M/s, $B$ forms at:
Half the rate of $A$.
Raising the temperature usually makes reactions:
More energetic collisions.
