Chapter 15, Problem 15.5TC

Interpretation Introduction

(a)

Interpretation:

Whether statement “A liquid vapor equilibrium is reached when the amount of liquid is equal to the amount of vapor” is true or false. In case of false statement true statement is to be written

Concept introduction:

Equilibrium is a state of reaction in which net change in any parameter is zero. Different reactions attain equilibrium at different conditions. Equilibrium conditions changes with change in number of moles, temperature, pressure and volume.

Interpretation Introduction

(b)

Interpretation:

Whether statement “Rate of evaporation depends on temperature”.is true or false. In case of false statement true statement is to be written.

Concept introduction:

Vaporization is the process in which liquid state is converted into vapor phase. Rate of vaporization is defined as the rate with the vaporization of liquid state is taking place. Rate of vaporization depends on physical parameters such as surface area and other factors.

Interpretation Introduction

(c)

Interpretation:

Whether the statement “Equilibrium vapor pressure is higher at higher temperatures” is true or false. In case of false statement true statement is to be written.

Concept introduction:

In equilibrium state, rate of formation of products is equal to the rate of consumption of reactants. According to gas law, pressure, volume and temperature are linked with each other. With the change in temperature, pressure and volume also changes. But for a constant volume change in pressure is dependent upon the change in temperature.

Gas equation is given below.

$\text{PV}=\text{nRT}$
