(c)
Interpretation:
Using the following equation sign of
The reaction is whether exothermic or endothermic has to be ascertained.
The reliability of the prediction with Le Chatelier’s principle has to be ascertained.
Concept Introduction:
Le Chatelier’s principle states that if a system undergoes change in temperature or pressure or concentration of its component, the equilibrium of the system will shift in a direction such a way that the system tend to counteract the effects caused by the change in temperature or pressure or concentration of its component.
