Reactions cannot occur without a certain minimum amount of energy. what is this amount of energy called?

Esure to answer all parts. the equilibrium constant for the reaction ni2+(aq) + 6 nh3(aq) ⇌ ni(nh3)6 2+(aq) is kf = 5.6 × 108 at 25°c. (a) what is δg o at this temperature? (b) if standard-state concentrations of reactants and products are mixed, in which direction does the reaction proceed? (c) determine δg when [ni(nh3)62+] = 0.010 m, [ni2+] = 0.0010 m, and [nh3] = 0.0050 m. in which direction will the reaction proceed to achieve equilibrium? (a) × 10 j/mol (enter your answer in scientific notation.) (b) to the right. to the left. (c) × 10 j/mol (enter your answer in scientific notation.) to the right. to the left.
