how does the average reaction rate differ from an instantaneous reaction rate?
a) the average reaction rate is how quickly the reaction proceeds over time. an instantaneous reaction rate is how quickly the reaction proceeds at a specific time.
b) the average reaction rate is how quickly the reaction proceeds over time considering the reactants. an instantaneous reaction rate is how quickly the reaction proceeds at a specific time considering the products.
c) the average reaction rate is how quickly the reaction proceeds at a specific time. an instantaneous reaction rate is how quickly the reaction proceeds over time.
d) the average reaction rate is how quickly the reaction proceeds over time. an instantaneous reaction rate is how quickly the reaction proceeds compared to another reaction.

Explanation:

To determine the correct answer, we analyze the definitions of average and instantaneous reaction rates. The average reaction rate measures the speed of a reaction over a period of time (a time interval), while the instantaneous reaction rate measures the speed at a specific moment in time.

• Option A: Matches the definitions (average over time, instantaneous at a specific time).
• Option B: Incorrectly introduces reactants and products as distinguishing factors, which is not part of the core definitions.
• Option C: Swaps the definitions (average should be over time, instantaneous at a specific time).
• Option D: Incorrectly defines instantaneous rate as a comparison to another reaction, which is not accurate.

Answer:

A) The average reaction rate is how quickly the reaction proceeds over time. An instantaneous reaction rate is how quickly the reaction proceeds at a specific time.
