Question
Chapter 9, Problem 2QAP
(a)
Interpretation Introduction
Interpretation:
The pressure of the vapors of benzene is to be calculated under the given conditions.
Concept Introduction :
The ideal gas equation is the expression that relates different measurable properties of a gas. The expression is given as:
where,
P = Pressure of the gas
V = Volume of the container in which the gas is occupied
R = Ideal gas constant = 0.0821 L atm/ mol K
n = number of moles of the gas = Mass of gas / Molecular mass of gas
T = Absolute temperature of the gas i.e., temperature on Kelvin scale
(b)
Interpretation Introduction
Interpretation:
The pressure calculated in part (a) are to be compared with the equilibrium pressures of benzene.
Concept Introduction :
If the pressure of vapors is more than the equilibrium pressure, it indicates that the liquid has undergone condensation.
(c)
Interpretation Introduction
Interpretation:
The pressure of benzene vapors inside the flask is to be calculated at 50 0C and 60 0C.
Concept Introduction : When a liquid is present in a closed container, it starts to form vapors above the liquid surface. A stage is reached when the liquid and vapors are present in equilibrium with each other.
