Chapter 17.2, Problem 15SSC

Interpretation Introduction

Interpretation:

In a given equilibrium the reason for more ${\text{CH}}_{\text{3}}\text{CHO}$ to be produced at lower temperature needs to be explained.

Concept introduction:

According to Le Chatelier’s principle, by lowering the temperature, equilibrium shifts towards the product side because the forward reaction releases heat and more products are formed.

Answer to Problem 15SSC

At the lowest temperature more products are formed as equilibrium is shifts towards right. So, in a given equilibrium reaction more ${\text{CH}}_{\text{3}}\text{CHO}$ is produced at lower temperature.

Explanation of Solution

According to Le Chatelier’s principle, when temperature is decreased then equilibrium is shifts towards the right side or product side and more products are formed. Thus relieves the stress of lowering of temperature.

A larger value of $\text{Keq}$ indicates that, there is high concentrations of products are formed with the relatively lower concentration of reactants. When temperature is changed then equilibrium is also changed.

Conclusion

At the lowest temperature more products are formed as equilibrium is shifts towards right. So, at the temperature $\text{263 K}$, more products are formed.
