Problem 11.50

Acetone $$\left(\mathrm{H}_{3} \mathrm{CCOCH}_{3}\right)$$ has a boiling point of $$56^{\circ} \mathrm{C}$$. Based on the data given in Figure 11.25, would you expect acetone to have a higher or lower vapor pressure than ethanol at $$25^{\circ} \mathrm{C}$$?

Text Transcription:

(H_3CCOCH_3)

56^{\circ} C

25^{\circ} C

Step-by-Step Solution:

Step 1 of 5) Collision frequency increases with temperature, A also has some temperature dependence, but this dependence is much smaller than the exponential term. Therefore, A is considered to be approximately constant. We can calculate the activation energy for a reaction by manipulating the Arrhenius equation. Taking the natural log of both sides of Equation 14.21, we obtain which has the form of the equation for a straight line. A graph of ln k versus is a line with a slope equal to and a y-intercept equal to ln A. Thus, the activation energy can be determined by measuring k at a series of temperatures, graphing ln k versus, and calculating Ea from the slope of the resultant line. We can also use Equation 14.22 to evaluate Ea in a non graphical way if we know the rate constant of a reaction at two or more temperatures. For example, suppose that at two different temperatures T1 and T2 a reaction has rate constants k1 and k2.
