Solution

Solution Steps

Step 1: Understanding the Potential Energy Diagram

The diagram shows the potential energy of reactants (A and B) and products (C and D) along with the transition state. Point 1 represents the energy of A and B, point 2 represents the energy of the transition state, and point 3 represents the energy of C and D.

Step 2: Analyzing the Effect of Increasing Concentration of A and B

Increasing the concentration of reactants (A and B) without changing the concentration of products (C and D) will shift the equilibrium position according to Le Chatelier's principle. This will favor the forward reaction, increasing the formation of products (C and D).

Step 3: Determining the Impact on ΔG and Equilibrium

ΔG (Gibbs Free Energy Change): Increasing the concentration of reactants will make the reaction more spontaneous, thus ΔG will become more negative.
Equilibrium Concentrations: The relative concentrations of A+B vs. C+D at equilibrium will change, favoring the formation of more products (C and D).

Final Answer

E. Only A and C are true
