Question
Chapter 16, Problem 12ST
Interpretation Introduction
Interpretation:
The direction of equilibrium shift after heating the reaction,
Concept introduction:
A reaction is said to be in equilibrium if the rate at which the forward reaction takes place becomes equal to the rate at which the backward reaction takes place. If any of the factors that affect the equilibrium changes, then the reaction shifts in either forward or backward direction so that the equilibrium condition is reestablished.
According to the Le Chatelier’s principle the change in concentration, volume, pressure and temperature affects the equilibrium of the reaction.
