 આપેલ \(:E _{ Cu ^{2} /  Cu }=0.34\, V ; E _{ Sn ^{2} / Sn }^{\ominus}=-0.14 \,V\) \(298\,K\) પર પ્રક્રિયા માટે ગિબ્સ મૂક્ત ઊર્જા ફેરફાર \(Cu ( s )+ Sn ^{2+}(0.001 \,M ) \rightarrow\,Cu ^{2+}(0.01 M )+ Sn ( s ), x \times 10^{-1}\, kJ \,mol ^{-1} s .\) [આપેલ : \(F =96500\,C\,mol ^{-1}\) ] તો \(x\) નું મૂલ્ય \(\dots\dots\) છે.

  1. A \(123\)
  2. B \(983\)
  3. C \(552\)
  4. D \(631\)
Verified Solution

Answer & Solution

Correct Answer

(C) \(552\)

Step-by-step Solution

Detailed explanation

\(Cu _{( s )} + Sn ^{2+}(0.001\, M ) \rightarrow Cu ^{2+}(0.01\, M )+ Sn _{( s )}\) \(E _{\text {cell }} = E _{\text {cathode }}^{\circ}- E _{\text {anode }}^{\circ}\) \(=-0.14-(0.34)\) \(=-0.48 \,V\)…
