Dissolution of which of these increases with temperature
Correct answer: D. KI
- A. Li2CO3
- B. LiCl
- C. NaCl
- D. KI
Explanation
KI's heat of soluion is endothermic and hence increasing the temperature will shift the system to products side making it more easy to dissolve . Other options have salt whose heat of solution is exothermic , making it more difficult to dissolve them.

About Chemical Equilibrium
Reversible reactions reach dynamic equilibrium when forward and reverse rates become equal, and Le Chatelier's principle predicts the effect of changing concentration, pressure or temperature. The chapter also covers solubility product, the common ion effect, buffer action and the conditions used in Haber's process, with equilibrium shifts distinguished from changes in the equilibrium constant.
