WebJan 30, 2024 · Since Ne is a gas, we can use our standard molar volume. Thus giving us: (2) 23.5 mL/L soln 1 mole Ne/22,414 mL = 0.00105 M. Now we have solved for the solubility of Ne in the solution. C= 0.00105M and we know the pressure at STP is 1 atm, so we can now use our rearranged equation: k = C P N e WebEquilibrium considerations The adsorption process can be considered a partitioning of the adsorbate between the fluid phase and the adsorbent. If the solid and fluid are placed in contact for a long time, an equilibrium distribution is reached, and this equilibrium can be described quantitatively.
