  2. A(g) + B(g)⇄AB(g) 2 particles 1 particle more pressure less pressure When the reaction shifts to the right it lowers the pressure When the reaction shifts to the left it increases the pressure

  3. Simulation A(g) + B(g)⇄AB(g) 50 Particles Shifting rightreduces the particles and the pressure

Stress Shift [HCl] [O2] [Cl2] ↑ [HCl] → ↑ ↓ ↑ ↓ [O2] ← ↓ ↓ ↑ Add water ― ― ― ― ↑ [Cl2] ← ↑ ↑ ↑ ↓ ↓ ↓ ← ↑ V When the volume increases all concentration go down
