Stoichiometry The vapor pressure of the solvent decreased by 10 mm Hg, when a non-volatile solute was added to the solvent. The mole fraction of the solute in the solution is 0.2. What should be the mole fraction of the solvent, if the decrease in vapor pressure of the solvent is required to be 20 mm Hg.? 0.1 0.2 0.6 0.4 0.1 0.2 0.6 0.4 ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry No cooling occurs, when an ideal gas undergoes unrestrained expansion, because the molecules Collide without loss of energy Exert no attractive force on each other Are above the inversion temperature Do work equal to loss in kinetic energy Collide without loss of energy Exert no attractive force on each other Are above the inversion temperature Do work equal to loss in kinetic energy ANSWER DOWNLOAD EXAMIANS APP
