2 cards from this section. Quick, good the night before a test.
Define the term 'reaction rate'.
Think about how we describe the speed of a chemical reaction.
What units are commonly used to express reaction rates?
Consider what quantities we measure in chemistry.
What is the average rate of reaction?
Consider the distinction we discussed between timeframes.
True or False: The units of reaction rate can differ based on the state of matter of the reactants.
Is the unit constant across different phases of matter?
Given the concentration of a reactant over 3 time intervals: 0.10 M, 0.08 M, and 0.06 M over the times 0 s, 50 s, and 100 s respectively, calculate the average rate over the first interval.
Break down the concentration change over the respective time.
An instantaneous rate is observed as 0.002 M/s at 30 seconds for a reaction. If the concentration at 30 seconds was 0.15 M, what would the new concentration be after 10 seconds?
Use the instantaneous rate to guide concentration changes over a time frame.
