In which of the following E= H ?

Options

  1. AN ₂ O ₄( ~g ) 2 NO ₂( ~g )
  2. B2 SO ₂(g)+ O ₂(g) 2 SO ₃(g)
  3. CH ₂(g)+ I ₂(g) 2 HI (g)
  4. DH ₂( ~g )+ 1 2 O ₂( ~g ) H ₂ O (l)

Correct answer

C. H ₂(g)+ I ₂(g) 2 HI (g)

Step-by-step solution

H= E+ n_g R T where n_g= number of moles of gaseous product - number of moles of gaseous reactant
