Distinguish between instantaneous rate and average rate. In each of the following situations, is the rate measured the instantaneous rate or the average rate? In a hot dog eating contest, it took the winner only 4 minutes to eat 20 hot dogs, so he ate 5 hot dogs per minute. At minute 1.0, the winner was eating 6 hot dogs per minute, but at minute 3.0, he was down to only 3 hot dogs per minute.

Distinguish between instantaneous rate and average rate.

In each of the following situations, is the rate measured the instantaneous rate or the average rate?

  1. In a hot dog eating contest, it took the winner only 4 minutes to eat 20 hot dogs, so he ate 5 hot dogs per minute.

  • At minute 1.0, the winner was eating 6 hot dogs per minute, but at minute 3.0, he was down to only 3 hot dogs per minute.
  • (a)

    Interpretation Introduction

    Interpretation:

    The difference between instantaneous and average rates must be explained and the given situation should be classified accordingly.

    Concept Introduction:

    • Chemical reactions proceed at a certain rate which is represented in terms of the change in concentration over a certain period of time
    • The rate can be expressed either in terms of a decrease in concentration of the reactants or an increase in the concentration of products.

    Explanation of Solution

    Instantaneous rate can be defined as the rate of a reaction at a particular instant in time. It is given by the slope of the line tangent to the curve at a single point.

    Average rate can be defined as the difference in the concentrations measured at two different times...
