amé: ID: A 6. Which statement about K is NOT true? It is affected by changes to the equilibrium system b. a. It has a numerical value. c. It can be used to determine the unknown concentration of a reactant. d. It can be used to determine the unknown concentration of a product. e. It has a unit of measure. 7. A homogeneous equilibrium involves chemicals that are a. b. c. d. in the same state, solid, liquid, or gas gases, liquids, or aqueous solutions gases or aqueous solutions gases only. 8. Which is true of the numerical value of the equilibrium constant, K? a. It represents the relative concentration of products compared with reactants b. It represents the ratio of reactants to products. c. It is measured in the SI unit, mole. d. Both a and c are true. e. Both b and c are true. 9, what does it mean if KeqExplanation / Answer
(6)
The incorrect statement is (a), because its value is not affected when we change the conc of species in the equilibrium system, its value only changes when we change the temperature.
(7)
In a homogeneous equilibrium, all the species are present in the same phase, whether solid, liquid or gas.
(8)
The correct statement is (a), because it is the ratio of the conc of products to the conc of reactants.
(9)
Keq < 1 means that the conc of reactants is greater than the conc of products.
