Use the information below to predict the characteristics of an equilibrium reaction 2A (aq) + 2Z (aq) ⇌ 2AZ (aq)        ΔG0 = -11.5 kJ/mol The value of the equilibrium constant for the reaction will be 1. 1.04 x 102 2. 9.64 x 10-3 3. 4.38 x 104 Which indicates that 4. The reaction is spontaneous in the forward direction 5. The reaction is spontaneous in the reverse direction And therefore 6. The concentration of reactants will be higher than concentration of products at equilibrium 7. The concentration of products will be higher than the concentration of reactants at equilibrium
