Question
pressure plays an vital role in the solubility of gas in liquid. Solubility is the amount of solute dissolved in solvent. With increasing in the pressure on the liquid system, solubility of gas in liquid increases.
As per Henry’s Law, at constant temperature, the mass of a gas dissolved per unit volume of solvent is directly proportional to the pressure of gas in equilibrium.
Solute - Solid substance
Solvent - Liquid substance.
Solute is mixed into solvent to form solution and solubility is the amount of a substance (solute) mixed in a particular solvent to form solution.When temperature increases -
the average kinetic energy of the liquid molecules increases. This increased kinetic energy makes the liquid molecules creating more space between them.With increase in temperature, the intermolecular forces holding the solid particles also decrease.
This leads to break them into smaller pieces and makes them readily take space vacant between the liquid particles. This way more solute is dissolved readily in liquid.Hence, the solubility increase with increase in temperature.

At high temperature synthesis gas will form carbon dioxide and hydrogen, and in fact this reaction is one of the ways hydrogen is made industrially. A chemical engineer studying this reaction fills a 75 L tank with 18. mol of carbon monoxide gas and 24. mol of water vapor. When the mixture has come to equilibrium he determines that it contains 6.0 mol of carbon monoxide gas, 12. mol of water vapor and 12. mol of carbon dioxide. The engineer then adds another 9.0 mol of carbon monoxide, and allows the mixture to come to equilibrium again. Calculate the moles of hydrogen after equilibrium is reached the second time.
