To calculate the e.m.f. of the cell for the given reaction, we will use the Nernst equation. The reaction is: \[ \text{Ni(s)} + 2\text{Ag}^+(0.004 \, \text{M}) \rightarrow \text{Ni}^{2+}(0.1 \, \text{M}) + 2\text{Ag(s)} \] ### Step 1: Identify the standard cell potential (E°cell) The standard cell potential is given as: \[ E^\circ_{\text{cell}} = 1.05 \, \text{V} \] ...
