Consider the greenhouse gases, CF2Cl2 and CH2CF2. These have the following properties: CF2Cl2: ΔGfo = -491 kJ/mol, atmospheric lifetime = 102 years, ozone depletion potential = 0.73 CH2CF2: ΔGfo = -451 kJ/mol, atmospheric lifetime = 5.4 years, ozone depletion potential = 0.0 Clearly, CH2CF2 is less hazardous in the atmosphere than CF2Cl2. Is it thermodynamically favorable under standard conditions to react CF2Cl2 with H2 gas to convert it to CH2CF2? (ΔGfo = 0 for H2 and Cl2) CF2Cl2 + H2 ⇌ CH2CF2 + Cl2 Justify your answer and calculate the equilibrium constant for this reaction.

Question
Consider the greenhouse gases, CF2Cl2 and CH2CF2. These have the following properties:
- CF2Cl2: ΔGfo = -491 kJ/mol, atmospheric lifetime = 102 years, ozone depletion potential = 0.73
- CH2CF2: ΔGfo = -451 kJ/mol, atmospheric lifetime = 5.4 years, ozone depletion potential = 0.0
Clearly, CH2CF2 is less hazardous in the atmosphere than CF2Cl2. Is it
CF2Cl2 + H2 ⇌ CH2CF2 + Cl2
Justify your answer and calculate the equilibrium constant for this reaction.
