Complete these equations: catalyst Ethene + Water Ethanol Ethanol can be made by two processes, ethene reacting with steam under pressure in the presence of a catalyst, or the fermentation of sugar using enzymes in yeast. Word bank: catalyst, sugar, yeast, steam catalyst C2H4 + H2O C2H5OH yeast Glucose Ethanol + Carbon Dioxide yeast C6H12O6 2 C2H5OH + 2CO2

  5. Use the table to compare advantages and disadvantages of making ethanol by fermentation versus hydration Draw the structural formula for ethanol C2H5OH below: Fermentation produces CO2 gas as a by-product. Fortunately it is a carbon neutral process. What does this mean? Overall the level of CO2 in the atmosphere remains unchanged as when the sugar cane is grown it removes carbon dioxide from the atmosphere by photosynthesis. Is ethanol a hydrocarbon? No Explain your answer Hydrocarbons contain hydrogen and carbon only. There is also an oxygen atom in ethanol. Why is a continuous process better than a batch process for making a product in industry? There is no downtime – a continuous process runs 24hrs a day, 7 days a week. Delete wrong answer Fermentation: Batch Hydration: Continuous
