Sample interview questions: How do you calculate the Gibbs free energy of a material?

Sample answer:

Calculation of Gibbs Free Energy

The Gibbs free energy (G) of a material can be calculated using the following equation:

G = H - TS

where:

• H is the enthalpy (heat content) of the material
• T is the absolute temperature
• S is the entropy (disorder) of the material

Steps to Calculate Gibbs Free Energy:

1. Determine the enthalpy (H):
2. Measure the heat flow into or out of the material in a constant-pressure environment using calorimetry.

3. Alternatively, use thermodynamic equations to calculate H from other known parameters.

4. Measure the temperature (T):

5. Use a thermometer or thermocouple to measure the temperature of the material in Kelvin.

6. Calculate t… Read full answer
