To calculate delta_H and delta_S for the two proteins, its enough to just calculate the slope and the y intercept for each graph.
For calculating the slope, we have the formula,
slope = change in y/change in x = dy/dx

Here, from the graph, we cannot find the exact values for dy and dx as the points are not clear. But its a very simple calulation which you can easily do.

Solution Summary

The solution explains each step and provides all mathematical steps.

What is Gibbs free energy? What is the difference between entropyandenthalpy? What does the useful work derived do such that the entropy increases (additional to that increased along with enthalpy) but enthalpy remains the same (i.e the useful work does not increase the enthalpy)?

Consider acetic acid, CH3COOH, The active ingredient in vinegar. It is also responsible for the sour taste of wine when gets exposed to air. Bacterial oxidation turns alcohol to acid.
