2 cards from this section. Quick, good the night before a test.
What is the unit of concentration in solutions?
Think about how we measure concentrations in a lab.
True or False: Higher concentrations lead to fewer collisions.
Consider how change in concentration affects collision frequency.
What is the primary effect of increasing the concentration of a reactant in a reaction?
Recall the relationship between collisions and concentration.
True or False: Concentration does not affect collision frequency.
Think about how the number of molecules can interact with each other.
Consider a reaction with a rate law Rate = k[A]^2[B]. If the concentration of A is tripled and B is held constant, how does the reaction rate change?
Think about the square relationship in the rate law.
If in a gas-phase reaction the partial pressure of A is increased from 1 atm to 4 atm while B remains constant, what is the expected change in reaction rate?
Consider how pressure mimics concentration in a gas.
