Question

Shown below are system representations of three equilibrium mixtures for the interconversions of B molecules to X, B molecules to Y, and B molecules to Z. The molecules of B are shown as yellow spheres while molecules of X, Y, or Z are green spheres. Determine the sign of ΔG° for each case.

Three diagrams showing equilibrium mixtures of B to X, Y, and Z with yellow and green spheres.

Accepted Answer
