A reaction with an equilibrium constant Kc = 1.5 x 10-25 would consist of which of the following at equilibrium:

Question

A. some reactants and products with products slightly favored
B. essentially all products
C. some reactants and products with reactants slightly favored
D. approximately equal reactants and products
E. essentially all reactants

Answer 1

K = (products)/(reactants). 1.5E-25 is a very small number. That means products must be small and reactants must be large.

Answer 2

ESSENTIALLY ALL PRODUCTS

Answer 3

1.5E-25 is a small number, so it would be E. essentially all reactants.
