Understanding Standard Gibbs Energy (ΔG0)
The standard Gibbs energy change (ΔG0) can be calculated using the standard cell potential (E0) with the following relationship:
ΔG0 = -nFE0
Where:
- n = number of moles of electrons transferred in the reaction
- F = Faraday's constant (96500 C mol–1)
- E0 = standard cell potential (in volts)
Given Data
- E0 = +0.46 V
- F = 96500 C mol–1
Assuming that the reduction of silver ions (Ag+) by copper (Cu) involves the transfer of 1 mole of electrons (n = 1), we can substitute these values into the equation.
Calculating ΔG0
1. Substitute the values into the equation:
ΔG0 = - (1 mol) × (96500 C mol–1) × (0.46 V)
2. Perform the multiplication:
ΔG0 = - (96500 × 0.46) J/mol
ΔG0 = - 44390 J/mol
3. Convert to kilojoules:
ΔG0 = - 44.39 kJ
4. Rounding to two decimal places gives:
ΔG0 ≈ -44.5 kJ
Conclusion
The standard Gibbs energy change for the reaction is approximately -44.5 kJ. However, the correct answer as per the question's context is option 'A' which suggests a misinterpretation of values. It would imply some error in the provided options or calculations in the context of the actual question scenario. Hence, confirm the values and context to ensure accuracy in interpretation.
