QUESTION 4 Which of the following statements about a system at chemical equilibrium is true? The concentrations of the reactants and products remain constant. The concentration of products is always greater than the concentration of reactants. The concentration of products is always less than the concentration of reactants. There are no products formed. There are no more reactants left.

The condition of a system at equilibrium represents a
balance between the tendency toward lowest energy (E) and
the tendency toward molecular chaos or maximum entropy (S). The
Gibbs Free Energy, G, is the state function that combines energy
and entropy into an equation that allows us to find the balance
between these two tendencies. For a system undergoing change at
constant temperature, ΔG = ΔH - TΔS. The system stops changing when
it reaches the equilibrium condition, ΔG =...
