Gibbs Free Energy G
« on: 24/04/2005 01:39:15 »
This is a basic question that I should know, but please bear with me.

Can anyone tell me what the difference is between  G  and G What does the   represent? Is the referring to a particular sytem whereas G is a general term?

Argghhh!! I can't find it anywhere.

Thanks, sincerely yours in embarrassment.[:I]

Oh, I just realised that delta came out as ! So, yeah, I'm talking about delta G.

Tia:D

Hm, I think it's the Gibb's Free Energy at standard temperature and pressure.
As the Gibb's energy can also be written (delta)G=(delta)H-T(delta)S Clearly temperature is important so you need to be specific about what temperature you're talking about.
Hope that helps.
I'm not sure if it's accessible, remotely but the (excellent) notes for the second year thermodynamics course at Cambridge are under "teaching materials" at http://www-teach.ch.cam.ac.uk/
Hope that helps.
