Question

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. question 8: what does an equilibrium constant k >> 1 indicate? the reaction rate is very fast. the products are favored at equilibrium. the reactants are favored equilibrium. there are equal concentrations of reactant and products at equilibrium.

Explanation:

Question 7

The equilibrium constant ($K$) is the ratio of the concentration of products to reactants at equilibrium. When $K = 1$, the concentrations of reactants and products are equal at equilibrium, meaning the forward and reverse - reaction rates are such that neither the formation of products nor reactants is favored.

The equilibrium constant $K=\frac{[products]}{[reactants]}$. When $K\gg1$, it means the concentration of products is much larger than the concentration of reactants at equilibrium, so the products are favored at equilibrium.

Answer:

The concentrations of reactants and products are equal
