Question

Consider two pure gases A and B, each at 25 °C and 1 atm pressure. Calculate the Gibbs energy
relative to the unmixed gases of
a) a mixture of 10 mol of A and 10 mol of B;
b) a mixture of 10 mol of A and 20 mol of B.
c) Calculate the change in Gibbs energy if 10 mol of B are added to the mixture of 10 mol of
A with 10 mol of B.

Answer 1

Explanation:

— When solids, liquids or gases are combined, the thermodynamic quantities of the system experience a change as a result of the mixing.
