Question

At a fixed temperature, equal moles of H₂ (g) and O₂ (g) are mixed in a constant pressure container (the volume of the container changes in order to keep the pressure at a constant value). The H₂ (g) and O₂ (g) are allowed to react, producing H₂O (g):

2 H₂ (g) + O₂ (g) → 2 H₂O (g)

If the initial volume of the container, before any reaction takes place, is 1.40 L, determine the volume of the container after the H₂ (g) and O₂ (g) have reacted to completion.

The final volume will be
