Final answer:
To fill in the table about equilibrium, if Q < Keq the reaction will move right (produce more products), if Q > Keq it will move left (produce more reactants), and if Q = Keq the system is at equilibrium with no net change.
Step-by-step explanation:
To complete the first row in the table about a system at equilibrium, we need to fill in the missing information based on the reaction quotient (Q) and the equilibrium constant (Keq).
For a system at equilibrium, not only is Q = Keq, but also the change in Gibb's free energy (ΔG) is zero. This relationship can be represented as 0 ΔG° + RT ln K at equilibrium.
