|
Negative Delta G |
rx pushed or runs to the right, "downhill", products, extensive, Q<K |
|
|
Positive Delta G |
rx pushed to the left, reactants, not extensive, Q>K |
|
|
Delta G of 0 |
ex not pushed, no driving forces to matter one way other another , not extensive, towards either products or reactants Q=K |
|
|
Delta G naught |
all reactants and products are in their standard state |
|
|
Standard States |
Solid-1 Liquid-1 Solutes- (A)/1.0 M Gases- P(A)/1.0 atm |
|
|
Q |
rx quotient, takes standard states into equation of products/reactants |
|
