New cards
What is reaction rate?
The change in amount of substance over time.
2
New cards
How do you calculate average reaction rate?
Rate = change in amount ÷ change in time.
3
New cards
What does a steep slope on an amount-time graph indicate?
A fast reaction rate.
4
New cards
What is instantaneous rate?
The rate at a specific point in time (tangent slope).
5
New cards
What happens to reaction rate as the reaction progresses?
It generally decreases as reactants are used up.
6
New cards
What type of data can be used to calculate rate?
Volume, mass, length, height, or temperature change.
7
New cards
How is product formation related to rate?
Faster formation = higher reaction rate.
8
New cards
Why is rate highest at the start?
Maximum concentration of reactants and collisions.
