Henry's law states that the amount of gas dissolved in a liquid is directly proportional to the partial pressure of that gas above the liquid, provided that the gas does not react with the solvent and that conditions such as pressure and temperature are not extreme.
Thus, the correct answer is: \( \text{(1) Gas reacts with solvent chemically.} \)
A binary mixture of benzene and toluene under vapour-liquid equilibrium at 80 \( ^\circ {C} \) follows ideal Raoult’s law. At this condition, the saturation pressures of benzene and toluene are 101 kPa and 40 kPa, respectively. If the mole fraction of benzene in the liquid phase is 0.6, the corresponding mole fraction of benzene in the vapour phase will be ________. (Round off to two decimal places)
Study the graph between partial pressure and mole fraction of some gases and arrange the gases P, Q, R, and S dissolved in H2O, in the decreasing order of their KH values.
If the ratio of lengths, radii and Young's Moduli of steel and brass wires in the figure are $ a $, $ b $, and $ c $ respectively, then the corresponding ratio of increase in their lengths would be:
