Assume each reaction is carried out in an open container. For which reaction will H= E ?

Options

  1. A2 CO _ ( g ) + O _ 2( ~g ) 2 CO _ 2( ~g )
  2. BH _ 2(g) + Br _ 2(g) 2 HBr _ ( g )
  3. CC _ ( s ) +2 H ₂ O _ ( g ) 2 H _ 2(g) + CO _ 2(g)
  4. DPCl _ 5(g) PCl _ 3(g) + Cl _ 2(g)

Correct answer

B. H _ 2(g) + Br _ 2(g) 2 HBr _ ( g )

Step-by-step solution

For ₂(g)+ Br ₂(g) 2 HBr (g) array ll & n_g=0 & H = E + n_g RT & H = E array
