Suppose you have a mole of water at 25°C and atmospheric pressure. Use the data at the back of this book to determine what happens to its Gibbs free energy if you raise the temperature to 30°C. To compensate for this change, you could increase the pressure on the water. How much pressure would be required?

QUESTION: Problem 10P
Suppose you have a mole of water at 25°C and atmospheric pressure. Use the data at the back of this book to determine what happens to its Gibbs free energy if you raise the temperature to 30°C. To compensate for this change, you could increase the pressure on the water. How much pressure would be required?
ANSWER:
Step 1 of 5
The expression for Gibbs free energy is;
Here is the entropy, is the change in temperature, is the change in pressure, is the volume and is the chemical potential.
