Which statement is correct?
When Q< Kthen AG = 1. When Q< K then AG=-AS When Q Kthen AG= 0. When Q> K then AG= 1. When Q> Kthen AG=- RT
If AG < 0 for a reaction, which of the following is/are true? Select all that apply. There will be no net change in the amounts of reactants or products. The reaction is spontaneous in the forward direction. The reaction is spontaneous in the reverse direction. The reaction is at equilibrium. The reaction will proceed to form more products. The reaction will proceed to form more reactants.
Please kindly explain why the answer is B, it a reaction is
less than Zero?
