Problem
Three separate reactions at 298 K have the following equilibrium constants:
• Reaction I: K=2.5×103
• Reaction II: K=0.80
• Reaction III: K=2.0×10−3
Rank the reactions from most product-favored to most reactant-favored, and identify which reaction, if any, will leave less than 5% reactant in the equilibrium mixture. Justify your choices in one or two sentences.
