Compare the equilibrium constants for the systems shown in the table. Which favors products the most? Which favors products the least? Rank these systems in order from most to least in terms of favoring products rather than reactants.A. D > B > A > C B. C > A > B > D C. B > C > D > A D. A > D > C > B (picture to show help me please)

Solution :

Predicting the Extent of a Reaction :

  • High value of equilibrium constant indicates that PRODUCT(s) concentration is high and its low value indicates that concentration of product(s) in equilibrium mixure is loe.
  • Large value of K (larger than about 10^3), favour the products strongly.
  • For intermediate value of K (approximately in the range of 10^{-3} to 10^3), the concentrations of reactants and products are comparable.
  • Small value of equilibrium constant (smaller than 10^{-3}), favour the reactants strongly.

C FAVORS products the most.

D favors products the least.
