(i) Write balanced equation for the direct combination of nitrogen and hydrogen.
(ii) Which of the metals - iron, platinum, copper - catalyse this direct combination?
(iii) Is the formation of ammonia promoted by high pressure or low pressure?

उत्तर
(i) The reactants nitrogen and hydrogen combine to form ammonia at low temperature, high pressure in presence of catalyst to for maximum yield of ammonia . The balanced equation for the reaction is:
\[\ce{N2 + 3H2 <=> 2NH3 +heat}\]
(ii ) Iron acts as catalyst.
(iii ) Since the forward reaction occurs with decrease in volume, according to Le Chatelier's principle, high pressure favours the formation of ammonia.
Key: Haber's process
