2 cards from this section. Quick, good the night before a test.
Define the rate of reaction.
Think about what happens to reactants and products during a reaction.
What is the difference between average rate and instantaneous rate?
Consider how you would measure speed over a distance vs speed at a specific point.
What is the average rate of disappearance of a reactant if it decreases from 0.20 M to 0.10 M over 10 seconds?
Calculate the difference first.
True or False: The instantaneous rate of a reaction is always greater than the average rate.
Remember that instantaneous rate refers to a very brief moment.
The concentration of a reactant A decreases from 0.250 M to 0.125 M over 100 seconds. Calculate the average rate and describe what happens instantaneously at 50 seconds.
Draw a graph if possible to visualize the changes.
Design an experiment to measure the effect of temperature on the rate of a reaction involving a solid catalyst.
Make sure you have proper safety measures when working with heat!
