This graph represents a population of molecules in a gas versus the distribution of the average velocity(speed) of its molecules

pshichka [43]

Answer:

Part A

Given that the graph is symmetrical and bell shaped, the average kinetic energy is given by the midline of graph, which corresponds to the common speed of the highest number of the population

Part B

The formula for the average kinetic energy, K.E. = (3/2)·(R/NA)·T

Therefore, the part of the graph that indicates the temperature of the sample is the average kinetic energy. K.E.

Part C

At a lower temperature, the heat is less evenly distributed and we have the distribution T2 higher than T1

What is its molar heat of vaporization in kilojoules per mole if its vapor pressure at 20°C is 11.0 torr?

NemiM [27]

Answer:

<em>H.vap = 6.544 kJ/mol</em>

Explanation:

Clausius-Clapeyron Equation

<em>In P = H.vap / RT</em> where T = 20 + 273 = 293K

H.vap = In P (RT) = In 11 (8.314 x 293) = 6543.861 J/mol = 6.544 kJ/mol
