3 cards from this section. Quick, good the night before a test.
What is a first order reaction?
Think about how the rate changes as reactant concentration changes.
How do you calculate half-life for a first order reaction?
What does the constant 'k' represent in this formula?
What defines a first-order reaction?
Focus on the definition of first-order reactions discussed.
Is the half-life for a first-order reaction dependent on the initial concentration?
Recall the formula for half-life for first-order reactions.
A first-order reaction has a half-life of 30 minutes. What will be the concentration after 90 minutes if the initial concentration is 1M?
Calculate how many half-lives fit into 90 minutes.
If k for a reaction is 0.1 min-1, calculate the rate of reaction when [R] is 0.5M.
Plug the values into the rate formula directly!
