Thermodynamics

Step 1: Use the Gibbs free energy equation.
The change in Gibbs free energy $%5CDelta%20G$ is given by the equation: $%5CDelta%20G%20%3D%20%5CDelta%20H%20-%20T%20%5CDelta%20S%2C$ where $%5CDelta%20H$ is the enthalpy change, $%5CDelta%20S$ is the entropy change, and $T$ is the temperature in Kelvin.

Step 2: Converting the values to consistent units.
- $%5CDelta%20H%20%3D%20-13.7%20%5C%2C%20%5Ctext%7Bkcal%2Fmole%7D$

- $%5CDelta%20S%20%3D%20-16.0%20%5C%20%5Ctext%7Bcal%7D%5C%2C%5Cmathrm%7BK%5E%7B-1%7D%5C%2Cmol%5E%7B-1%7D%7D%20%3D%20-0.016%20%5C%20%5Ctext%7Bkcal%7D%5C%2C%5Cmathrm%7BK%5E%7B-1%7D%5C%2Cmol%5E%7B-1%7D%7D$

- $T%20%3D%2025%5E%5Ccirc%20%5Ctext%7BC%7D%20%3D%20298%20%5C%2C%20%5Ctext%7BK%7D$

Step 3: Substituting into the equation.
$%5CDelta%20G%20%3D%20-13.7%20-%20(298)(-0.016)%2C$ $%5CDelta%20G%20%3D%20-13.7%20%2B%204.768%20%3D%20-8.932%20%5C%2C%20%5Ctext%7Bkcal%2Fmole%7D.$

Step 4: Conclusion.
The value of $%5CDelta%20G$ is $%5Cboxed%7B-8.93%7D%20%5C%2C%20%5Ctext%7Bkcal%2Fmole%7D$ .
