The gaseous reaction A+B 2 C+D+Q is most favoured at

Options

  1. Alow temperature and high pressure
  2. Bhigh temperature and high pressure
  3. Chigh temperature and low pressure
  4. Dlow temperature and low pressure

Correct answer

D. low temperature and low pressure

Step-by-step solution

For the reaction A+B 2 C+D+Q As the reaction is exothermic, low temperature favours formed direction according to Le-Chatelier's principle. Also n_ (g) =(2+1)-(1+1)=1 aligned n_ g =&+ ve & (low pressure favours forward direction) aligned Low pressure and temperature favours formed direction for the reaction.
