Reactions in chemical production
Answers are for parents and teachers.
1
In N₂ + 3H₂ ⇌ 2NH₃ + Q, how should pressure and temperature change to raise the yield (from the equilibrium point of view)?
Pressure up, temperature down (the reaction releases heat).
2
With γ = 3, how many times does the rate grow from 40 °C to 60 °C?
9
3
In 2NO + O₂ → 2NO₂, how many times does the rate grow if [O₂] is tripled and [NO] doubled?
12
4
If 200 L (STP) of an N₂ and H₂ mixture (1 : 3) is fully converted to NH₃, how many litres of NH₃ form?
100
5
Why does industry aim to run reactions under “optimal conditions”?
For high yield and rate, low use of raw materials and energy, and cheap, safe products.
