Question

State and explainvtwo conditions under which the intesity of the brown colour of the equlibrium mixture can be increased

a)condition1
b)condition2​

Answer 1

a) The intensity of the brown color of the equilibrium mixture can be increased if the concentration of the reactants is increased. This is because the reaction leading to the formation of the brown product is an equilibrium reaction, and according to Le Chatelier's principle, increasing the concentration of the reactants will shift the equilibrium towards the products, resulting in more brown product being formed.

b) The intensity of the brown color of the equilibrium mixture can also be increased if the temperature is increased. This is because the reaction leading to the formation of the brown product is exothermic, and according to Le Chatelier's principle, increasing the temperature will shift the equilibrium towards the endothermic reaction, resulting in more brown product being formed.
