Question

calcium hydroxide Cao2 shows a dash of solubility with that dash of temperature​

Answer 1

Answer:

i) Solubility of calcium oxide decrease on increasing temperature because it is an exothermic reaction and on increasing temperature, equilibrium shifts to backward direction and solubility decreases.

ii) In exothermic reactions, on increasing temperature solubility decreases and on decreasing temperature the solubility increases.

iii) In endothermic reaction, on increasing temperature the equilibrium shifts to forward direction and solubility increases.

iv) On increasing the pressure the kinetic energy of the gaseous particles increases and the solubility of gas increases.

this is the easy process I have written
