Chemistry · JEE Main · NTA Exams — Redox Reactions and Electrochemistry

For the cell reaction,

\(\begin{array}{c} \mathrm{Cu}^{2+}(\mathrm{aq})+\mathrm{Zn}(5) \rightarrow \mathrm{Zn}^{2+}(\mathrm{aq})+\mathrm{Cu}(5) \\ \mathrm{C}_{2} \end{array}\)

of an electrochemical cell, the change in free energy, ΔG, at a given temperature is a function of:

  1. \(\mathrm{In} \mathrm{C}_{1}\)
  2. \(\ln \left(\frac{C_{2}}{C_{1}}\right)\)  
  3. \(\mathrm{In} \mathrm{C}_{2}\)
  4. \(\ln \left[c_{1}+c_{2}\right]\)

Answer

(B) ( C_ 2 C_ 1 )
