LO-1Analyse and interpret data to determine the impact of reagents and reaction conditions on yield and rate of chemical synthesis processes. Macromolecules: polymers, proteins and carbohydratesLO-2Apply amino acid symbols to construct and name tripeptides.LO-3Calculate the yield of chemical synthesis reactions by comparing stoichiometric quantities with actual quantities and by determining limiting reagents and/or reaction conditions.LO-4Describe, using equations, how - addition polymers, including polyethene (LDPE and HDPE), polypropene and polytetrafluorethene, can be produced from their monomers - condensation polymers, including polysaccharides (carbohydrates), polylactic acid (PLA), polyamide (proteins and nylon) and polyester, can be produced from their monomers.LO-5Describe, using equations, the - production of ammonia by the Haber process - production of sulfuric acid using the contact process - production of ethanol from fermentation and the hydration of ethene - operation of a hydrogen fuel cell under acidic and alkaline conditions.LO-6Explain that reagents and reaction conditions are chosen to optimise the yield and rate for chemical synthesis processes, including the production of ammonia (Haber process) and sulfuric acid (contact process).LO-7Identify that disaccharides are formed when monosaccharides monomers are joined by glycosidic bonds. Chem istry 2025 v1.3 The following subject matter may be assessed in the internal assessments.LO-8Identify that tripeptides are formed when amino acid monomers are joined by peptide bonds.LO-9the Haber and contact processes*LO-10the properties of polymers. *Note: Simulations may be used.
