JEE Mains · Chemistry · STD 12 - 2. Electrochemistry

\(Cu ( s )+2 Ag ^{+}( aq ) \rightarrow Cu ^{2+}( aq )+2 Ag ( s )\) अभिक्रिया का दिया गया साम्य स्थिरांक, \(K _{ C ^{\prime}}\) \(10 \times 10^{15}\) है। \(298 K\) पर इस अभिक्रिया के \(E _{\text {cell }}^{+}\) की गणना कीजिए। \(\left[2.303 \frac{ RT }{ F } \text { at } 298 K =0.059 V \right]\)

  1. A \(0.04736\,mV\)
  2. B \(0.4736\,mV\)
  3. C \(0.4736\,V\)
  4. D \(0.04736\,V\)
Verified Solution

Answer & Solution

Correct Answer

(C) \(0.4736\,V\)

Step-by-step Solution

Detailed explanation

\(\Delta {G^o}\, = \, - \,nFE_{cell}^o\,\) \( = \, - \,2.303\,RT\,\log \,{K_{eq}}\) \(2FE_{cell}^o\, = \,2.303\,RT\,\log \,{K_{eq}}\) \(2E_{cell}^o\, = \,\frac{{2.303\,RT}}{F}\,\log \,10\, \times \,{10^{15}}\) \(E_{cell}^o\, = \,\frac{{0.059}}{2}\,\, \times \,16\)…
