Ammonia is synthetically by reaction
N2 +3H2 ---> 2NH3
(a) The process is exothermic. This is because heat is released during the formation of NH3(ammonia)
(b) The moles of NH3 formed when 1 mole of N2 reacted with hydrogen is 2 moles
by use of mole ratio between N2 to NH3 wich is 1:2 the moles of NH3 is therefor = 1 x 2/1 = 2 moles
(c) The moles of NH3 produced if 18 x10^23 molecules of H2 reacted is 1.993 moles of NH3
calculation
by use of Avogadro law constant calculate the moles of H2 reacted
1 mole = 6.02 x 10^23 molecules
? = 18 x10 ^23 molecules
by cross multiplication
= 1 mole x 18 x10 ^23 / 6.02 x10^23 = 2.99moles of H2
by use of mole ratio of H2 : NH3 which is 3:2 the moles of NH3 is therefore= 2.99 x/3=1.993 moles
