Final answer:
The equilibrium constant (K) value that indicates a reaction system containing very little product at equilibrium is d) K= 1.0 X 10^-14. This value suggests an equilibrium heavily favoring reactants over products.
Step-by-step explanation:
When determining which K value indicates a reaction system that contains very little product when equilibrium is reached, we are referring to the equilibrium constant (K). The equilibrium constant provides insight into the relative quantities of reactants and products at equilibrium. A small K value indicates that at equilibrium, the reactants have little tendency to form products, and hence, the system will contain essentially only reactants.
Given the options:
- K = 1.0 X 10^0
- K = 1.0 X 10^14
- none of these
- K = 1.0 X 10^-14
The correct answer is K= 1.0 X 10^-14, which signifies that the reaction system at equilibrium has a very small ratio of products to reactants, and therefore, contains very little product.
