Question

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

1. Nitrogen gas is treated with hydrogen gas in the presence of a catalyst at 773 K to form ammonia gas.
2. Potassium hydroxide solution is treated with acetic acid to form potassium acetate and water.
3. Ethanol is warmed with ethanoic acid to form ethyl acetate in the presence of concentrated H₂SO₄.
4. Ethene is burnt in the presence of oxygen to form carbon dioxide, water and release heat and light. 

Answer 1

 

(a)	`"N"_2("g") + 3"H"_2("g") overset("Catalyst" ("Pt"))underset(773"K")(->) 2"NH"_3("g")`	Combination reaction
(b)	`"KOH"("aq") + underset("Acetic  acid")("CH"_3"COOH"("aq")) -> underset("Pot.  acerate")("CH"_3"COOK"("aq")) + "H"_2"O"("l");`	Double displacement or neutralisation reaction.
(c)	`underset("Ethanol")("C"_2"H"_5"OH"("l")) + underset ("Ethanoic  acid") ("CH"_3"COOH"("l")) overset ("H"_2"SO"_4("Conc".))(->) underset("Ethyl  ethnoate") ("CH"_3"COOC"_2"H"_5("l")) + "H"_2"O"("l")`	Double displacement or Esterification  reaction.
(d)	`underset("Ethene")("C"_2"H"_4("g")) + 3"O"_2("g") -> 2"CO"_2("g") + 2"H"_2("g") + "heat" + "light";`	Combustion or Redox reaction.
