Which of the following reactions shows work of compression?

Options

  1. ANH _ 3( ~g ) + HCl ( g ) NH ₄ Cl _ ( s )
  2. BC ₂ H _ 6( ~g ) 2 C _ ( s ) +3 H _ 2( ~g )
  3. C2 SO _ 3( ~g ) 2 SO _ 2( ~g ) + O _ 2( ~g )
  4. D2 H ₂ O _ 2( ) 2 H ₂ O _ ( ) + O _ 2( ~g )

Correct answer

A. NH _ 3( ~g ) + HCl ( g ) NH ₄ Cl _ ( s )

Step-by-step solution

NH _ 3( ~g ) + HCl _ ( g ) NH ₄ Cl _ ( s ) In this reaction, gaseous reactant converted into solidified product which resulting in a decrease of volume and shows work of compression.
