**Heat of vaporization**can be solved using the**Clasius-Clapeyron equation**where:

Where P is pressure (any unit will do as long as P1 and P2 have the same unit) and T is temperature in K.

**ΔHvap**is*heat of vaporization*in J/mol while R is gas constant (8.314 J/mol K)Plugging in the values of P and T from the table provided (I'll be using 255 K and 265 K but any will do):

The vapor pressure of carbon tetrachloride is measured as a function of temperature and the results are tabulated and shown in the table below. Determine the heat of vaporization of carbon tetrachloride from the results.

Temperature (K) | Pressure (torr) |

255 | 11.3 |

265 | 21.0 |

275 | 36.8 |

285 | 61.5 |

295 | 99.0 |

300 | 123.8 |
