State le chatelier's principle . Mention the effect of temperature and pressure on the equilibrium constant
Answers
Explanation:
le chateliers principle it states that at change in any of the factors that determine the equilibrium conditions of a system will cause the system to change in in such a manner so as to reduce or to counteract the effect of the change
effect of temperature
increase in temperature of system favours endothermic reaction
decrease in temperature of system favours exothermic reaction
effect of pressure change
on increasing the pressure of reaction mixture the reaction proceeds in forward direction so as there is a decrease in volume in forward reaction
on decreasing the pressure of reaction mixture the reaction proceeds in backward direction as there is an increase in volume in backward direction
Answer:
(1) The effect of temperature on solubility depends on enthalpy of solution.
(2) For example, dissolution of KCI in water is an endothermic process Since heat 1s absorbed dunng dissolution. In this according to Le Chatelier's principle by increasing temperature the solubility of KCI increases.
3) Dissolution of CaCl_2. Li_2SO_4. H_2O in water is an exothermie process since heat is evolved during dissolution. In this, according to Le Chateliers principle by increasing the temperature the solubility decreases.
