Question 31

Chemical Equilibrium

2CO(g) + O2(g) ⇌ 2CO2(g)
In the reaction above, high pressure will favour the foward reaction because

  1. A.high pressure favours gas formation
  2. B.the reaction is in dynamic equilibrium
  3. C.the reaction is exothermic
  4. D.the process occurs with a decrease in volume.
Show the answer and explanation

Answer: D (the process occurs with a decrease in volume.)

Explanation

3 volumes of gas become 2, so the forward reaction reduces the volume, which high pressure favours.
