The combination of /_\H and -T/_\S must be NEGATIVE, indicating a release of total free energy.

 

Thus:

 

/_\G = /_\H - T/_\S

Posted

If Delta H were negative that would mean that the chemical system would lose energy to the surroundings and that should make the products more stable. /_\ represents the total energy exchange that takes place between the system and its environment and T/_\ represents the energy eused to take care of the intermolecular activity.

think Endothermic and Exothermic reactions, Gibbs is all rellated to that as well as the initial "trigger energies" for the reaction to take place, Gibbs is the "Maths Bit" :)

yup! that`s about it :)

 

sorry for repeating same info as Wolfson, he must type faster than me (not hard to do today, I`m in alot of pain with my hands)

Wolfson, probably knows alot more about the maths and calc side than myself, he`s worth listening to! :)

dS = C ln (T2 / T1)

 

C = heat capacity.

 

then,

 

dG = dH - T dS

 

so i got it wrong on the test.
