Question

question 5: what does the equilibrium expression represent? the ratio of product to reactant concentrations at the beginning of a reaction the ratio of reactant to product concentrations at the beginning of a reaction the ratio of reactant to product concentrations at equilibrium the ratio of product to reactant concentrations at equilibrium question 6: what does an equilibrium constant k >> 1 indicate? the reaction rate is very fast. the products are favored at equilibrium. the reactants are favored at equilibrium. there are equal concentrations of reactant and products at equilibrium. question 7: if the equilibrium constant for a reaction is 1, what can be inferred about the system at equilibrium? the system favors the formation of products the system favors the formation of reactants the concentrations of reactants and products are equal the reaction does not occur

Explanation:

Question 5:

The equilibrium constant $K$ is the ratio of product - to - reactant concentrations at equilibrium. A large $K$ ($K\gg1$) means that the concentration of products is much higher than that of reactants at equilibrium, so the products are favored at equilibrium.

When the equilibrium constant $K = 1$, the ratio of product concentrations to reactant concentrations at equilibrium is 1. This implies that the concentrations of reactants and products are equal at equilibrium, and the system does not favor the formation of either reactants or products.

The equilibrium expression represents the ratio of product concentrations to reactant concentrations at equilibrium, with each concentration raised to the power of its stoichiometric coefficient in the balanced chemical equation.

Answer:

The products are favored at equilibrium.
