Explanation / Answer

1) we know that dG 0 =-RT lnK

so -13.458 x 1000 = - 8.314 x 700 x lnk

k= 10.09

Kp is 10.09

2) Eo cell = Eo cathode - Eo anode

Eocell = Eo Ni+2/Ni - Eo Ba+2/Ba

Eo cell = -0.23 + 2.91

E cell = 2.68

Eo cell is 2.68

As Eo is positive the reaction is spontaneous

So reaction is spontaneous and EO cell is 2.68 V

3) by the addition of HCl , forming insoluble metal chlorides .
