Stoichiometry The ratio of existing moles of vapor per mole of vapor free gas to the moles of vapor that would be present per mole of vapor free gas, if the mixture were saturated at the existing temperature & pressure, is termed as the Relative saturation Percentage saturation None of these Relative humidity Relative saturation Percentage saturation None of these Relative humidity ANSWER DOWNLOAD EXAMIANS APP
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 Do work equal to loss in kinetic energy Do not lose energy on collision Do not exert attractive force on each other Are above the inversion temperature Do work equal to loss in kinetic energy Do not lose energy on collision Do not exert attractive force on each other Are above the inversion temperature ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry The heat evolved in the combustion of benzene is represented by the equation: C₆H₆ + 7.5 O₂ = 6CO₂ + 3H₂O, ΔH = 3264.6 kJ/kg. mole The heat energy change, when 39 gm of C₆H₆ is burnt in an open container, will be __________ kJ/kgmole. +1632.3 -2448.45 +816.15 -1632.3 +1632.3 -2448.45 +816.15 -1632.3 ANSWER DOWNLOAD EXAMIANS APP
