Question

Predict the direction a reaction will proceed based on ΔG. How do you get a -ΔG (spontaneous reaction)?

Answer 1

When ΔG is negative, the reaction is spontaneous in the forward direction. When ΔG is positive, the reaction is spontaneous in the reverse direction. When ΔG is zero, there is no net reaction and the system is at equilibrium.

Step-by-step explanation:

If ΔG is less than zero, E is greater than zero and K is greater than 1, then the direction of the reaction is spontaneous in the forward direction. If ΔG is greater than zero, E is less than zero and K is less than one, then the direction of the reaction is spontaneous in the reverse direction. If ΔG is zero, E is zero, and K is one, then there is no net reaction and the system is at equilibrium.
