Chlorobenzene boils at 131.8C. Use Trouton's Rule to estimate deltaH of vaporization.
Answered by lada
can you please show all the steps?
Answered by lada
one more question please:

Calculate the delta S of vaporization for each of the liq: acetone, dimethyl ether, ethanol, octane, pyridine.

their delta H of vaporization are 29.1, 21.5, 38.6, 34.4, 35.1.

how do I do this????
Answered by DrBob222
1. Svap = about 87 J/mol*K = (delta Hvap/boiling pt). Substitute 131.8 for boiling point and calculate delta Hvap.

2. Use the same equation shown in 1 and substitute for delta Hvap and boiling point to determine delta Svap. The idea behind this question is to show that not ALL compounds obey Trouton's Rule, especially those that experience hydrogen bonding and/or those materials that tend to form dimers, trimers, or other polymeric forms.

how do you get 87J/molK
Answered by lada
is the answer to question 1: 35.22 ( if temperature changed to K)?
