Hi to everyone at the forum.(adsbygoogle = window.adsbygoogle || []).push({});

I've attached the question in word format so you can see it properly but

it is basically this:

-----

The Gibb's Free Energy is:

G(T, P, N) = U - TS + PV

Where N is the number of particles. (Only one type of particle is present).

Explain why the N-dependence of G is given by:

G(T, P, N) = Ng(T, P)

Where g(T, P) is independent of N.

-----

So far the only thing I can think is that the number of particles, N, is not dependent on anything else and can be factored out. But to be honest I don't understand the question very well and can see how my answer (if it is an answer) is rather flimsy.

Thank you for any help you can give,

Ben
