Question

(9 ) 12 (9 ) 98. Silver chloride is a slightly soluble compound. It dissociates to form ions as shown in this equilibrium: AgCl (s) Ag+ (aq) + 2Cl(aq) AH° = +65.1 kJ/mol Indicate whether these changes would shift the equilibrium to the left or to the right: a. adding Cl ions b. removing Agions c. increasing the temperature

Answer 1

98)
a)
Adding product will shift the reaction in the direction of reactant as per Le chatelier Principle
So, Equilibrium moves to reactant side
Answer: to the left

b)
Removing product will shift the reaction in the direction of product as per Le chatelier Principle
So, Equilibrium moves to product side
Answer: to the right

c)
Increasing Temperature will shift the reaction in a direction which absorbs heat as per Le chatelier Principle
Forward reaction is endothermic in nature
hence, forward reaction will be favoured
So, Equilibrium moves to product side
Answer: to the right
