Stoichiometry The boiling points for pure water and pure toluene are 100°C and 110.6°C respectively. Toluene and water are completely immiscible in each other. A well agitated equimolar mixture of toluene and water are prepared. If, at a total pressure of one standard atm. exerted by the vapours of water and toluene, the mole fraction of water Xw in the vapour phase satisfies 0.5 < Xw < 1.0 Xw = 1.0 Xw = 0.5 0 < Xw < 0.5 0.5 < Xw < 1.0 Xw = 1.0 Xw = 0.5 0 < Xw < 0.5 ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry At a constant volume, for a fixed number of moles of a gas, the pressure of the gas increases with rise of temperature due to Decrease in mean free path Increase in average molecular speed Increase in molecular attraction Increased collision rate among molecules Decrease in mean free path Increase in average molecular speed Increase in molecular attraction Increased collision rate among molecules ANSWER DOWNLOAD EXAMIANS APP
