Interpretation Introduction

Interpretation:

To find out the average rate of the reaction between 0 and 10 seconds.

Concept Introduction:

Change in concentration of any product or reactant with respect to time is called as the rate of reaction.

Correct answer:

Option (a) is correct and options (b), (c) and (d), are incorrect.

Explanation of Solution

Reason for the correct option:

The concentrations at 0 s and 10 s are marked as:

Chemistry: Structure And Properties, Global Edition, Chapter 15, Problem 1SAQ

The average between 0 and 10 seconds is calculated as:

  averagerate=-Δ[A][Δt]=-[M-0.86 M][0s-10s]=0.014M/s

Thus, option (a) is correct.
