The correct interpretation of the equation below is:?
Fe3+(aq) + SCN¨C(aq)¡ú FeSCN2+(aq)
A. The reaction is incomplete because the product is still charged.
B. A heterogeneous equilibrium exists because of the charged ions.
C. The equilibrium constant is Kc = [Fe3+][SCN¨C][FeSCN2+]
D. At equilibrium, the rate of the forward reaction equals the rate of the reverse reaction.
E. None of these.
I think its E because c is def wrong. the others don't make much sense.
The correct answer is D.
At equilibrium, the forward rate equals the reverse rate.
thanks
The correct interpretation of the equation Fe3+(aq) + SCN-(aq) → FeSCN2+(aq) cannot be determined from the given information because the answer options provided do not accurately describe the equation. However, option D is the closest interpretation to the concept of equilibrium. At equilibrium, the rate of the forward reaction equals the rate of the reverse reaction, implying that the reaction has reached a balanced state. Therefore, option D can be considered as the best interpretation out of the given options.
To determine the correct interpretation of the given equation, let's analyze the options:
A. The reaction is incomplete because the product is still charged.
This interpretation does not seem valid because the presence of a charged product does not necessarily imply an incomplete reaction. It may suggest an ionic compound or a complex ion formation.
B. A heterogeneous equilibrium exists because of the charged ions.
A heterogeneous equilibrium occurs when the reactants and products are present in different phases (e.g., solid, liquid, gas). However, since all the species in this equation are aqueous ions (indicated by (aq)), it does not exhibit a heterogeneous equilibrium.
C. The equilibrium constant is Kc = [Fe3+][SCN¨C][FeSCN2+]
This interpretation is incorrect because the equilibrium constant expression is calculated by raising the concentration or activity of the products to their stoichiometric coefficients and dividing by the reactants' coefficients. In this case, the equilibrium constant expression would be Kc = [FeSCN2+]/([Fe3+][SCN−]) instead of the given form.
D. At equilibrium, the rate of the forward reaction equals the rate of the reverse reaction.
This interpretation is known as the principle of microscopic reversibility. According to this principle, at equilibrium, the rates of the forward and reverse reactions are equal. Since the equation is balanced and shows a reversible reaction, it is likely that the correct interpretation is D.
E. None of these.
While E may seem like a possibility, the correct interpretation can be deduced by elimination. Based on the analysis above, option D seems to be the most suitable interpretation of the equation.
Therefore, the correct interpretation of the equation is:
D. At equilibrium, the rate of the forward reaction equals the rate of the reverse reaction.
