For the cell reaction
\(2 F e^{3+}(a q)+21^{-}(a q) \rightarrow 2 F e^{2+}(a q)+1_{2}(a q)\)
\(E_{t e l l}^{\ominus}=0.24 \mathrm{~V}\) at 298 K. The standard Gibbs energy (ΔrGΘ) of the cell reaction is: [Given that Faraday constant F = 96500 C mol-1]
- -46.32 kJ mol-1
- -23.16 kJ mol-1
- 46.32 kJ mol-1
- 23.16 kJ mol-1
Answer
(A) -46.32 kJ mol -1
