Gibbs Free Energy

Question 1

G= kJ/mol

Answer 1

G= H - TS

Question 2

Reaction is spontaneous when?

Answer 2

H,G<0; E>0

Question 3

Reaction is non spontaneous when?

Answer 3

G,H>0; E<0

Question 4

Reaction is at equ when?

Answer 4

G,H=0

Question 5

3 limitations?

Answer 5

1. Limited to systems at standard conditions
   - > G is temp dependent
2. G< 0 may not occur
   -> rate of reaction is extremely slow
   => thermodynamically feasible; kinetically unfeasible

Question 6

G= J/mol

Answer 6

-nFE
