. Write the balanced chemical equations for the following reactions and identify the type of reaction in each case.


(a) Nitrogen gas is treated with hydrogen gas in the presence of a catalyst at 773K to form ammonia gas.
 
(b) Sodium hydroxide solution is treated with acetic acid to form sodium acetate and water.
 
(c) Ethanol is warmed with ethanoic acid to form ethyl acetate in the presence of concentrated H2 SO4.
 
(d) Ethene is burnt in the presence of oxygen to form carbon dioxide, water and releases heat and light.

Best Answer

Answer: (a) N2(g)+3H2(g)= catalyst 773K2NH2(g)

Option (a) is a combination reaction.
 
(b) NaOH(aq)+CH3COOH(aq)⟶CH3COONa(aq)+H2O(l)
 
Option (b) is a neutralisation reaction between a strong base and a weak acid.
 
(c) C2H5OH(aq)+CH3COOH(l)⟶CH3COO C2H5(aq)+H2O(t)
 
Option (c) is a neutralisation reaction and double displacement reaction.
 
(d) C2H4(g)+3O2(g)→2CO2(g)+2H2O(g)+ Heat + Light
