Question

1. what information is provided by the magnitude of the equilibrium constant k?

a. the temperature at which the reaction is carried out
b. the initial concentrations of the reactants and products
c. whether products or reactants are favoured
d. an indication of how rapidly equilibrium will be achieved
e. none of the above

Explanation:

• Option a: The equilibrium constant \( K \) is not related to the temperature's value for reaction execution (temperature affects \( K \) but \( K \)'s magnitude doesn't show the reaction's temperature).
• Option b: \( K \) depends on equilibrium concentrations, not initial concentrations of reactants and products.
• Option c: The magnitude of \( K \) (e.g., \( K \gg 1 \) favors products, \( K \ll 1 \) favors reactants) tells us whether products or reactants are favored at equilibrium.
• Option d: \( K \) has no relation to the rate at which equilibrium is achieved (kinetics, not thermodynamics/equilibrium constant, determines reaction rate).

Answer:

c. Whether products or reactants are favoured
