Chapter 19, Problem 7STP

Interpretation Introduction

Interpretation:

On increasing the temperature of an equilibrium reaction, the shift of equilibrium is to be discussed for endothermic reactions.

Concept introduction:

The concept involves the study of Le-Chatlier’s principle. This principle studies about the shift of equilibrium by change in temperature, pressure and volume of equilibrium mixture.

According to it,

By changing temperature, pressure or volume equilibrium shifts towards the direction which compensates the effect of change.

Answer to Problem 7STP

B

Explanation of Solution

Endothermic reactions are favored by temperature. Because in endothermic reactions heat is required, this is given by increase in temperature. Thus, on increasing the temperature, equilibrium will shift towards the right. So option B is correct.

Conclusion

• Option A is incorrect because endothermic reactions are favored by temperature.
• Options C and D are incorrect because equilibrium has no effect on rate of reaction.
