What is GFE used for

The feasibility of a reaction is determined by the balance between ΔH and ΔS° which is what GFE is.

2
New cards

Formula for GFE

∆G = ∆H – T∆S

T= ∆H/(∆S/1000)

ALWAYS DIVIDE T∆S BY 1000

If ∆G is -ve the reaction is feasible and vice versa.

3
New cards

When might a reaction not be feasible even when ∆G <0

A very high Ea

A kinetically inert system
