Consider the following reaction at 298K. Cu2+ (aq) + Ag (s) Cu+ (aq) + Ag+ (aq) Which of the following statements are correct? Choose all that apply. Eocell < 0, K < 1, delta Go < 0, n = 1 mol electrons, The reaction is product-favored.,

Transcript

00:01 The standard free energy change of an electrochemical reaction is computed as delta g knot equals negative nf times delta times e nut cell where e not cell is the standard or is the standard free cell potential of an electrochemical reaction so here we denote that we take note that if e cell is a positive value your delta g knot is a negative value and if it's negative then you would have your k to be greater than zero indicating that the reaction is spontaneous and that in other words it is product favorite so what we will do first in this problem is that we will separate the overall reaction into half reactions so we will do that by collecting common species such as n a 2 plus then with n i and then the remaining will be ag and then a g and then a 2a2 plus plus 2 a g to plus and then we will balance this by adding electrons on the side that we need to decrease the charge on so for the first reaction we need to reduce the charge on the left side by 2 we put the two electrons there and then on the other equation we put it on the product side so we see here that the reaction for the first reaction is seen to be on is seen on the reaction is seen on the reactants side it is the reduction reaction as electrons are gained and the other reaction will be oxidation since electrons are lost now from the from the standard reduction potential table the reduction potential for these reactions are as follows so for nickel we have a nickel 2 plus we have it as negative 0 .23 of volts where for us for ag plus it's 1 .99 volts where for us for ag plus it's 1 .99 volts now this is unlikely to happen because the reduction reaction should have a more positive errant for the reaction to be spontaneous.

02:21 That means oxidation reaction should have more negative erred.

02:25 But it doesn't appear to be, that rule appears not to be followed here...
