Specific Latent Heat using Trouton's Rule Solution

STEP 0: Pre-Calculation Summary

Formula Used

Specific Latent Heat = (Boiling Point*10.5*[R])/Molecular Weight
L = (bp*10.5*[R])/MW
This formula uses 1 Constants, 3 Variables

Constants Used

[R] - Universal gas constant Value Taken As 8.31446261815324

Variables Used

Specific Latent Heat - (Measured in Joule per Kilogram) - The Specific Latent Heat is energy released or absorbed, by a body or a thermodynamic system, during a constant-temperature process.
Boiling Point - (Measured in Kelvin) - Boiling Point is the temperature at which a liquid starts to boil and transforms to vapor.
Molecular Weight - (Measured in Kilogram) - Molecular Weight is the mass of a given molecule.

STEP 1: Convert Input(s) to Base Unit

Boiling Point: 286.6 Kelvin --> 286.6 Kelvin No Conversion Required
Molecular Weight: 120 Gram --> 0.12 Kilogram (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

L = (bp*10.5*[R])/MW --> (286.6*10.5*[R])/0.12

Evaluating ... ...

What does Trouton's Rule state?

Trouton’s rule states that the entropy of vaporization is almost the same value, about 85–88 J K−1 mol−1, for various kinds of liquids at their boiling points. The entropy of vaporization is defined as the ratio between the enthalpy of vaporization and the boiling temperature. It is named after Frederick Thomas Trouton.
