Vedclass · Answer

(A) According to Le Chatelier's principle,for an endothermic process,the dissolution can be represented as: $	ext{Solute} + 	ext{Solvent} + 	ext{Heat} ightleftharpoons 	ext{Solution}$. When the temperature is increased,the equilibrium shifts in the forward direction to absorb the extra heat,thereby increasing the solubility of the solute. The reason statement is also correct because a saturated solution represents a state of dynamic equilibrium where the rate of dissolution equals the rate of crystallization. Since the shift in equilibrium due to temperature change is explained by Le Chatelier's principle,$(R)$ is the correct explanation for $(A)$.

Assertion $(A)$: For an endothermic dissolution process,an increase in temperature increases the solubility in a nearly saturated solution.
Reason $(R)$: In a saturated solution,dynamic equilibrium exists between the dissolved solute and the undissolved solute.

Identify a solution which contains a solid as the solute and a liquid as the solvent.

Give an example of a solid solution in which the solute is a gas.

If $CO_2$ gas having a partial pressure of $1.67 \ bar$ is bubbled through $1 \ L$ water at $298 \ K$,the amount of $CO_2$ dissolved in water in $g \ L^{-1}$ is approximately. (Henry's law constant of $CO_2$ is $1.67 \ kbar$ at $298 \ K$)

The Henry's law constant for the solubility of $N_2$ gas in water at $298 \ K$ is $1.0 \times 10^5 \ atm$. The mole fraction of $N_2$ in air is $0.8$. Calculate the number of moles of $N_2$ dissolved in $10 \ moles$ of water at $298 \ K$ and a total pressure of $5 \ atm$.
