Examine the vapor pressure curve for ethanol in Figure 11.12. (a) What is the approximate vapor pressure of ethanol at 40 °C? (b) Are liquid and vapor in equilibrium when the temperature is 60 °C and the pressure is 600 mm Hg? If not, does the liquid evaporate to form more vapor, or does vapor condense to form more liquid?

(a)

Interpretation Introduction

Interpretation:

Using the vapor pressure identify whether water will vaporize at 400C and find out answer the following.

Concept Introduction:

Vapor pressure is nothing but the pressure of a vapor in contact with its liquid or solid form.

When a liquid and vapor are in equilibrium the pressure exerted by the vapor is called the equilibrium vapor pressure.

Explanation

When a liquid and vapor are in equilibrium the pressure exerted by the vapor is called the equilibrium vapor pressure.

From the table the vapor pressure of ...
