A system is in equilibrium with its envornment at a common temperature and a common pressure. The entropy of the system is increased slightly (by a fluctation in which heat flows into the system, or by the purposeful injection of heat into the system). Explain the implication of both the Le Chatelier and the Le Chatelier-Braun principles to the ensuing processes, proving your assertions in detail.

I don't know how to start with this.

I know form the book that if I have a spontaneous fluctuation [tex]dX_1^f[/tex] in my composite system then this fluctuation will be accompanied by a change in intensive parameter [tex]P_1[/tex] of the subsystem, and then I have this equation:

[tex]dP_1^f=\frac{\partial P_1}{\partial X_1}dX_1[/tex]

And that the fluctuation [tex]dX_1^f[/tex] also alters intensive parameter [tex]P_2[/tex]

[tex]dP_2^f=\frac{\partial P_2}{\partial X_1}dX_1[/tex]

This is how the book explains it, then it makes a reasoning based on the responses. The thing is I don't know how to relate this with the specific problem I'm dealing with, I don't know how to use the fluctuation on the entropy, and I don't know which kind of responses that will produce.

Would you help me?

Thanks in advance. Bye there!
