Chapter 18, Problem 74A

Interpretation Introduction

Interpretation: The amount of product at equilibrium in a spontaneous reaction and a nonspontaneous reaction is to be compared.

Concept introduction: A reaction is said to be spontaneous if the conditions under which it is taking place are such that the reaction favors the production of products. A nonspontaneous reaction is one in which the generation of products is not favored under the given conditions.

Answer to Problem 74A

In a spontaneous reaction, there is a higher amount of product at equilibrium as compared to the nonspontaneous reaction.

Explanation of Solution

Spontaneous reactions occur fast, resulting in the formation of more products. Therefore, equilibrium at the amount of product formed by a spontaneous reaction is significantly higher than the amount of product formed by a nonspontaneous reaction.

Conclusion

In a spontaneous reaction, there is a higher amount of product at equilibrium as compared to the nonspontaneous reaction.
