Analyzing the choices
A. True since the change is between the starting point (our reactant) and the ending point (product)
The diagram shows the free energy change of the reaction. A(g) + B(g) ⇌ AB(g) The reaction progress starts on the left with pure reactants, A and B, at 1 atm and moves to pure product, AB, also at 1 atm on the right. Select the true statements.
A. The "x" on the graph corresponds to ΔG of this reaction.
B. The minimum on the graph corresponds to the equilibrium position of the reaction.
C. At equilibrium, all of A and B have reacted to form pure AB.
D. The difference between the top left of the curve and the bottom of the curve corresponds to ΔG of this reaction.
E. The entropy change for the reaction is positive.
