Card 1 of 20
What does the rate of a reaction tell you?
A
A rate graph is usually steepest at the start because the most reactant is present, and becomes flat when the reaction has finished.
B
How quickly a reactant is used up or a product is made.
C
Time how long the reaction takes to hide a mark under the flask.
D
The mean rate is an average rate, so it does not show that the reaction is fastest at the start.
