APFIVE Le Châtelier's Principle and Concentration
After adding a reactant to a system at equilibrium, a researcher observes a shift toward the products. The researcher concludes that adding a reactant will always increase the product yield. Which statement best identifies the flaw in this conclusion?
A
The shift depends on the reaction’s stoichiometry and other conditions.
B
Adding reactants decreases the yield of products, not increases.
C
Concentration changes do not affect the position of equilibrium.
D
The yield of products is determined by the reaction’s temperature.
