Stoichiometry The activity co-efficient of a solution, which accounts for the departure of liquid phase from ideal solution behaviour Is not dependent on the temperature Is a function of the liquid phase composition Measures the depression in freezing point Measures the elevation in boiling point Is not dependent on the temperature Is a function of the liquid phase composition Measures the depression in freezing point Measures the elevation in boiling point ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry Unrestrained expansion of an ideal gas does not result in its cooling due to the reason that the gas molecules Are above the inversion temperature Do work equal to loss in kinetic energy Do not exert attractive force on each other Do not lose energy on collision Are above the inversion temperature Do work equal to loss in kinetic energy Do not exert attractive force on each other Do not lose energy on collision ANSWER DOWNLOAD EXAMIANS APP
