b)
i) NH3 decomposes according to the following reaction
Hence, we will get N2 and H2 in the reaction mixture after the reaction is complete.
ii)
The number of molecules of each product formed is
and
iii)
The simplest ratio of molecules of reactants and products can be calculated by dividing their ratio with a common factor,
The ratio is
Hence, the simplest ratio is .
iv)
The balanced equation is
Hence, the coefficients of the balanced reaction matches with the simplest ratio of the molecules of reactants and products,.
That is , 2 moles of NH3 decomposes to form 1 mole of N2 and 3 moles of H2.
