question 48

Multiple Choice

When a mixture of 3-phosphoglycerate and 2-phosphoglycerate is incubated at 25 °C with phosphoglycerate mutase until equilibrium is reached, the final mixture contains six times as much 2-phosphoglycerate as 3-phosphoglycerate. Which statement is MOST nearly correct, when applied to the reaction as written? (R = 8.315 J/mol · K; T = 298 K) 3-phosphoglycerate $\rightarrow$ 2-phosphoglycerate
