Transcribed Image Text:**Electrochemical Cell Potential Calculation**
This section provides a detailed example of calculating the potential for each half-cell and the total electromotive force (EMF) at 25 °C for the following electrochemical cell representation:
**Cell Representation:**
- Anode: \( \text{Pb} / \text{Pb}^{2+} \text{ (0.001 N)} \)
- Cathode: \(\text{Cl}^- \text{ (0.1 N)} / \text{Pt, Cl}_2 \text{ (1 atm)}\)
**Standard Electrode Potentials:**
- \( E^\circ_{\text{Pb}^{2+}/\text{Pb}} = -0.126 \, \text{V} \)
- \( E^\circ_{\text{Cl}_2/\text{Cl}^-} = +1.358 \, \text{V} \)
**Objective:**
Calculate the potential for each half-cell and determine the total EMF of the cell.

- Request: Can you please help me with answering the following question? Do what you can and thank you for your help. Question: The following problems involve one mole of an ideal monatomic gas, CP = 5R/2, in a variable volume piston/cylinder with a stirring paddle, an electric heater, and a cooling coil through which refrigerant can flow (see figure in images). The piston is perfectly insulated. The piston contains 1 g-mole of gas. Unless specified, the initial conditions are: T i = 25oC, P i = 5 bar. (a) Status: Heater on; cooler off; paddle off; piston fixed. Five kJ are added by the heater. Find ΔU, ΔS, ΔP, and ΔT. (b) Status: Heater off: cooler off; paddle off; piston moveable. What reversible volume change will give the same temperature rise as in part (a)? Also find ΔU, ΔS, and ΔP. (c) Status: Heater off; cooler off; paddle on; piston fixed. What shaft work will give the same ΔU and ΔS as in part (a)?arrow_forwardPls do correct and only handwritten i need pls okly handwrittenarrow_forwardPlease Show all stepsarrow_forward
