Chemistry

1. By using the Clausius-Clapeyron equation,lnP=??HvapRT+C, derivethe relationship between the vapor pressures, P1 andP2, and the absolute temperatures at which they weremeasured, T1 and T2.

Express your answer in terms of T1, T2,?Hvap, and the gas constant R.

ln(P1/P2)=

2.

Gasoline is a mixture of hydrocarbons, a major component ofwhich is octane, CH3CH2CH2CH2CH2CH2CH2CH3. Octane has a vaporpressure of 13.95 torr at 25?C and a vapor pressure of 144.78 torrat 75?C. Use these data and the equation in part (a) to calculatethe heat of vaporization of octane.

Express your answer using two significant figures.

3.

By using the equation in part (a) and the data given in part(b), calculate the normal boiling point of octane.
