In which of the following reactions, an increase in the volume of the container will favour the formation of products?

Options

  1. A4 NH 3   g +   5 O 2   g ⇌   4 NO g +   6 H 2 O ( l )
  2. B2 NO 2   ( g )   ⇌   2 NO ( g )   +   O 2 ( g )
  3. C3 O 2 ( g ) ⇌ 2 O 3 ( g )
  4. DH 2 ( g ) + I 2 ( g ) ⇌ 2 H I ( g )

Correct answer

B. 2 NO 2   ( g )   ⇌   2 NO ( g )   +   O 2 ( g )

Step-by-step solution

Volume ↑         P ↓ reaction proceed in the direction where number of gaseous moles increase. 2 N O 2   g ⇌   2 N O g +   O 2   g         ∆ n g = 2 + 1 - 2 = 1
