2 cards from this section. Quick, good the night before a test.
What does a linear plot of ln(concentration) versus time indicate?
Think about how the rate relates to concentration.
How can you determine if a reaction is second-order using a graph?
Consider what relationship you know between concentration and time for second-order reactions.
What indicates a first-order reaction when graphed?
Remember the relationship of ln versus time for first-order reactions.
True or False: A second-order reaction will yield a straight line when plotting concentration vs. time.
Think about what you learned regarding plotting methods for different reaction orders.
Given a reaction with a half-life of 5 minutes, determine whether it is first or second order if the initial concentration is known.
Use the half-life relationship for both orders.
For a reaction where plots of ln([A]) and 1/[A] were made, the ln plot was linear, but the 1/[A] plot was not. What does this indicate?
Refer back to plotting principles for reaction orders.
