Stoichiometry The activity co-efficient of a solution, which accounts for the departure of liquid phase from ideal solution behaviour Is a function of the liquid phase composition Is not dependent on the temperature Measures the depression in freezing point Measures the elevation in boiling point Is a function of the liquid phase composition Is not dependent on the temperature Measures the depression in freezing point Measures the elevation in boiling point 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 molecular attraction Increase in average molecular speed Increased collision rate among molecules Decrease in mean free path Increase in molecular attraction Increase in average molecular speed Increased collision rate among molecules ANSWER DOWNLOAD EXAMIANS APP

Stoichiometry A perfectly insulated container of volume V is divided into two equal halves by a partition. One side is under vacuum, while the other side has one mole of an ideal gas (with constant heat capacity) at 298 K. If the partition is broken, the final temperature of the gas in the container Will be greater than 298 K Can not be determined Will be 298 K Will be less than 298 K Will be greater than 298 K Can not be determined Will be 298 K Will be less than 298 K ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry For a reacation, X → Y, if the concentration of 'X' is tripled; the rate becomes nine times. The order of reaction is 3 1 2 3 1 2 ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry The density of a gas 'X' is twice that of another gas 'Y'. If the molecular weight of gas 'Y' is 'M'; then the molecular weight of the gas 'X' will be M/2 M M/4 2M M/2 M M/4 2M ANSWER DOWNLOAD EXAMIANS APP
