Is the following reaction spontaneous at 50°c? ag/ag'(0.0078 m)||ni2 (0.023 m) ni
Answers: 1
= +ve, reaction is spontaneous
![E_{cell}=E^o_{cell}-\frac{2.303RT}{nF}\log \frac{[Ag^{+}]}{[Ni^{2+}]^2}](/tpl/images/0212/6601/d4ce1.png)
= standard electrode potential =
are standard reduction potentials.![E^0_{[Ag^{+}/Ag]}= +0.80V](/tpl/images/0212/6601/c732a.png)
![E^0_{[Ni^{2+}/Ni]}= -0.23V](/tpl/images/0212/6601/476c4.png)
![E^0=E^0_{[Ni^{2+}/Ni]}- E^0_{[Ag^{+}/Ag]}](/tpl/images/0212/6601/494e8.png)
![E_{cell}=-1.03 - \frac{2.303\times 8.314\times 323}{2\times 96500}\log \frac{[0.0078]}{[0.023]^2}](/tpl/images/0212/6601/bfed6.png)
