Q: 26. Using the standard electrode potentials given in the Table 8.1, predict if the reaction between the following is feasible:

(A)

(B)

(C)

(D)

(E)

Answer

(A) The possible reaction between is given by,

for the overall reaction is positive. Thus, the reaction between and

is feasible.

(B) The possible reaction between is given by,

positive for the overall reaction is positive. Hence, the reaction between and

is feasible

(C) The possible reaction between and is given by

positive for the overall reaction is positive. Hence, the reaction between and is feasible.

(D) The possible reaction between and is given by,

Here, E° for the overall reaction is negative. Hence, the reaction between and is not feasible.

(E) The possible reaction between and is given by,

Here, E° for the overall reaction is positive. Hence, the reaction between and is feasible.
