Question

For a chemical system that is in dynamic equilibrium with Kc = 0.50, which of the following statements is FALSE? The rate of conversion of reactants to products is the same as the rate of conversion of products to reactants From the perspective of the forward reaction, the reaction mixture at equilibrium lies in favor of the products Both reactants and products are present in the reaction mixture The composition of the reaction mixture does not change with time The equilibrium constant describing the mass ratio of products to reactants in the chemical system does not change unless the temperature is changed

Answer 1

reaction the nale not At dynamic equilibrium nale of the forward equals of reverse reaction amount of products reactants do not revusible reaction because the amount change of substance channing into reactants from products is to amount equal of substance changing from reactants to products Trefore the amount of products & reactanti remains constant The rate of conversion of reactanto to products is the same as the rate of conversion of products h neactants True Stalement Smilarly the composition of the reaction mixture does with time change True statement the k (equilibrium constant) gives some information reactant & produit concentrations at equilibrium. K = 0.50 mostly reactant species present at equilibrium. Here it stalement from the perspective of formand Maction, the reaction mixture at equilibrium lies in the favor of the product" is false k (equilibrium instant) depends only temperature Beraline herce the equilibrium crustant change unless the temperature is charged - Tone station of k hes belveen ool & 1000 I ken we have significant onunfaction of both reactant & product present asequilibrium. Bolu reactants & produits are present in the reaction mix - Tomeski- magnitude of abont is small which we will Lene > ke 32 valme of ow ares het (" nine

hence 2nd statement re from the perspective of the forward reaction The reaction mixline at equilibrium lies in favour of the products, 2 is talse.
