Role Play Script: Gibbs Energy and Feasibility of Cell Reaction

---

Characters:

• Gibbs Free Energy (G)
• Cell Reaction
• Positive ΔG
• Negative ΔG
• Battery/Cell
• External Energy Source (optional character)

---

Scene 1: Introduction

(Gibbs Free Energy enters, wearing a badge “G”)

Gibbs Free Energy:
"Hello everyone! I am Gibbs Free Energy. I decide whether a reaction will happen by itself or not!"

---

Scene 2: Cell Reaction Enters

(Cell Reaction comes in, confused.)

Cell Reaction:
"I want to know... will I move forward on my own? Or do I need a push?"

---

Scene 3: ΔG Comes to Help

(Positive ΔG enters, confidently.)

Positive ΔG:
"If ΔG is positive, the reaction is non-spontaneous. You won't happen by yourself! You’ll need external energy!"

(Negative music or sad sound.)

(Negative ΔG enters, smiling.)

Negative ΔG:
"But if ΔG is negative, then the reaction is spontaneous. You will happen naturally without any help!"

*(Cheerful music.)

---

Scene 4: Battery/Cell Enters

(Battery/Cell comes running in, holding a big sign: "E°cell")

Battery/Cell:
"Hey friends! I am the Battery! I have something important to say:"

Delta G = -nFE_{cell}

Battery/Cell continues:
"If my E°cell is positive, then ΔG becomes negative, and the reaction is spontaneous!"

"But if my E°cell is negative, then ΔG becomes positive, and reaction won't happen unless external energy is supplied!"

---

Scene 5: Final Message

(All gather together. Gibbs Free Energy speaks.)

Gibbs Free Energy:
"So remember, if ΔG is negative, the reaction is feasible and spontaneous. If ΔG is positive, it is non-feasible and needs energy!"

(All together shout cheerfully:)
"Know your ΔG, know your Reaction!"

---

Optional Props/Visuals:

• Flashcards:
  • “Spontaneous = Negative ΔG”
  • “Non-Spontaneous = Positive ΔG”
• A chart showing the formula:

  G = -nFE_{cell}

• Happy/sad emojis for Negative ΔG / Positive ΔG.
