Question

ammonia is formed from the reactants nitrogen and hydrogen in the presence of a catalyst under suitable conditions. assuming all volumes are measured in litres at s.t.p. calculate the volume of ammonia formed if only 10% conversion has taken place​

Answer 1

Explanation:

The reaction for the formation of ammonia:

N2 + 3H2 → 2NH3

It can be seen that 1 mole of N2 and 3 moles of H2 together 4 moles of reactants produce 2 moles of ammonia

If only 10% conversion takes place,

0.4 moles of reactants will produce 0.2 moles of ammonia

At STP, in term of molar volume:

0.4 x 22.4 = 8.96 L of reactants will produce 0.2 x 22.4 = 4.48 L of ammonia.
