Question

A reaction with an equilibrium constant Kc = 1.5 x 1021 would consist of which of the following at equilibrium:
A) approximately equal reactants and products
B) some reactants and products with reactants slightly favored
C) some reactants and products with products slightly favored
D) essentially all reactants
E) essentially all products

Answer 1

K = (products)/(reactants) = 10^21
How do you get such a large number? With products high and reactants low. So E is the only answer that makes sense. Right?
