When a chemical reaction comes to equilibrium, both the forward and the reverse reactions continue, but their rates are equal. For such a system at equilibrium at 300 K and 1.00 atm pressure, the change in Gibbs free
energy as the forward reaction occurs must be
1. a maximum.
2. zero.
3. negative.
4. a minimum.
5. positive.

Answer 1

What is delta G at equilibrium?

Answer 2

I think that's what I'm looking for.

Answer 3

Isn't delta G at equilibrium zero?

Answer 4

thanks
