C61.1 Haber and contact process + fertilsers 0.0 / 5 ? ChemistryHaber and industrial processesGCSEOCR Created by: JULIASTOREYCreated on: 23-02-20 11:29 Mineral deficiencies in plants Nitorgen(N), Phosphorus(P), Potassium(K) 1 of 18 What do they cause? N- poor growth, yellow leaves; P- poor root growth, discoloured leaves; K- Poor fruit growth, dicoloured leaves 2 of 18 What does the Harber Process manufactor? Ammonia from nitorgen and hydrogen 3 of 18 Equation is... N2(g) + 3H2 /\ 2NH3 4 of 18 Raw materails the Haber Process uses? air, natural gas, and steam 5 of 18 Nirtogen is manufactored via ... fractional distillation 6 of 18 Hydrogen is manufactored by ... reacting natural gases (mainly methane) with steam 7 of 18 What is a batch process? Making a small amount at a time 8 of 18 What is an continuous process? Industial process which is when they make large amounts that goes oon all the time. 9 of 18 Conditions of the Haber process: -pressusre of 200 atmospheres, -temp of 450'C, -an iron catalyst 10 of 18 Why does the Haber process cool the ammonia? So the ammonia can be removed and unreacted Nitogen and Hydrogen to be recyled, improving the overall yield to 97% 11 of 18 What are the three raw materials needed for making sulfuric acid: -Sulfuric acid, -air(oxygen), -water 12 of 18 What happens in stage 1 of contact process? Sulfur burns in the air to produce sulfur dioxide 13 of 18 What happens in stage 2 of contact process? Sulfur dioxide and oxygen react together to make sulfur trioxide. 14 of 18 The conditions for this reverible reaction is; -pressure of 2 atmospheres, -temp of 450'C, -a Vadium oxide catalyst (V2O5) 15 of 18 What is the equilibrium yield under these conditions? 96% 16 of 18 What happens in stage 3: Sulfur trioxide is converted to sulfuric acid, by reacting it with water 17 of 18 Why is stage 3 carrid out in two steps? Stage 3 is very exothermic so producesa hazardous acidic mist. 18 of 18
