Interpretation:
The effect of increase in temperature on concentration of product is to be determined.
Concept introduction:
Le- Chatelier’s principle states that whenever there is a change in temperature, pressure or concentration of a reaction, equilibrium shifts in a direction to nullify the effect.
Answer to Problem 120A
Rising of temperature will decrease the amount of product.
Explanation of Solution
In the given reaction
It means heat is released in the process.
Thus, on increasing temperature, according to Le- Chatelier’s principle equilibrium will shift towards reactants
In nutshell, all exothermic reactions are not favored by temperature. They are favored at low temperature values.
