Question

Question 13 1 pts A chemical system with a large equilibrium constant is usually associated with negative values of A Gº. Which description of this system is correct? The forward reaction is spontaneous and mostly products are present. The forward reaction is spontaneous and mostly reactants are present. The reverse reaction is spontaneous and mostly reactants are present The reverse reaction is spontaneous and mostly products are present. At equilibrium, equal amounts of reactants and products are present. At equilibrium neither the forward, nor reverse reaction occur. Question 14 1 pts Which of the reactions is/are redox reactions? 2Li(s) + Cl2le) - UICI(s) HCl(aq) + LIOH(aq) → H2O(1)+LICl(aq) OKCIO3(s)KCIO(s) + O2(e) Ca(NO3)2(aq) Na2CO3(aq) -2NaNO3(aq) +CaCO3(s) Ca(NO3)2(s) - 2NO3(aq) + Ca?"(aq)

Answer 1

equilibriuen constant and Anil A system with large with negative values of in favoured in the forward reaction and thus, mostly products are formed. Also, at equilibriumg both the forward and backward reactions occur but with the same rate, So, the answer is the @ The forward reaction se spontaneous and mostly products are presente Analy Redox.rons are those reactions that o in which the oxidation states of the regateste elements change.
