Redox Reactions And Electrochemistry Ques 603

Question: For the reduction of silver ions with copper metal, the standard cell potential was found to be $+ 0.46 V$ at $25^{\circ} C .$ The value of standard Gibbs energy, $Δ G^{\circ}$ will be $(F = 96500 C m o l^{- 1})$

Options:

A) $- 89.0, k J$

B) $- 89.0, J$

C) $- 44.5, k J$

D) $- 98.0, k J$

Show Answer

Answer:

Correct Answer: A

Solution:

[a] $C u + 2 A g^{+} (a q) \overset{}{\to} C u^{2 +} (a q) + 2 A g (s)$ Here $n = 2, E_{c e l l}^{^{\circ}} = + 0.46 V$ $Δ G^{\circ} = - n E^{\circ} F$ $= \frac{- 2 \times 0.46 \times 96500}{1000} k J ≃ - 89 k J$
