Following reaction occurs at 25°C :
2NO (g, 1 × 10 –5 atm) + Cl 2 (g, 1 × 10 –2 atm) 
2NOCl (g, 1 × 10 –2 atm)
Calculate Δ G° [R = 8 J/mole K]
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(– 43.92 KJ)
Sol. 2NO (9, 1 × 10 –5 atm) + Cl 2 (9, 1 × 10 –2 ) 2NOCl (9, 1 × 10 –2 )
Δ G° = – 2.303 
= – 2.303 RT 
= – 2.303 RT [log 1 × 10 8 ] = – 2.303 × 8 × 298 × 8 = – 43.92 KJ
