Consider the reaction at 300 K
H2(g) + Cl2(g)  2HCl(g) ΔH° = -185 kJ
If 3 mole of H2 completely react with 3 mole of Cl2 to form HCl. What is ΔU° for this reaction ?
  • a)
    0
  • b)
    -185 kJ
  • c)
    555 kJ 
  • d)
    None of these
Correct answer is option 'D'. Can you explain this answer?
Verified Answer
Consider the reaction at 300 KH2(g) + Cl2(g)2HCl(g) ΔH° = -1...
For 3 moles of Cl2 & HCl
ΔU = – 3 × 185 = – 555 kJ
