The diagram for the free energy of the reaction

A(g) + B(g) ⇌ AB(g)

The reaction progress starts on the left with pure reactants, A and B, each at 1 atm and moves to pure product, AB, also at 1 atm on the right.

Select the true statements.

a. The difference between the top left of the curve and the minimum of the curve corresponds to ΔG standard.
b. The "x" on the graph corresponds to ΔG standard.
c. The minimum on the graph corresponds to the equilibrium position of the reaction.
d. The entropy change for the reaction is positive.
e. At equilibrium, all of A and B have reacted to form pure AB. What scientific concept do you need to know in order to solve this problem?
