Which of the below statements are correct about the process : gas + solvent satu

Question

Which of the below statements are correct about the process : gas + solvent saturated solution a) The change in enthalpyis usually negative. b) If the temperature of thesolution decreases the equilbrium shifts to the left. c) Cooler water in contact with the atmosphere contains moredissolved oxygen at equlibrium that water at a higher temperature. d) Thermal pollution is a problem for aquatic life asthe warming of streams and rivers by industrial facilities reducesthe concentration of oxygen in these waters.

Explanation / Answer

We Know that :      Gas + Solvent ------>Solution       In the above case the gas actsas solute .      The Change in Enthalpy is usuallyNegative it signifies the Reaction is Exothermic i.e the case ofideal gas condition.    So the statement is true.       If the temperature of thesolution decreases the equilibrium lies towards the forwarddirection as the forward reaction is      accompained with the evolution ofheat. So the statement is true with respect to Hesse's law .        Cooler water in contactwith the atmosphere contains more dissolved oxygen as at lowertemperature the diffusion of           gasesis not possible so their is more amount of oxygen gas present inthe solution.        Thermal Pollution makesthe evolution of Oxygen gas at faster rate so the dissolvedoxygen in the atmosphere decreases.
