What are the advantages/disadvantages of using the hydration of ethene to manufacture ethanol.Advantages: Fast rate of reaction. Pure product. Disadvantages: Uses finite resources, e.g crude oil cane. Uses high temp and pressure therefore high energy input. Uses batch process which is inefficient.Advantages: Uses continuous process which is efficient. Fast rate of reaction. Disadvantages: Uses finite resources, e.g crude oil cane. Uses high temp and pressure therefore high energy input. Impure product.Advantages: Uses continuous process which is efficient. Fast rate of reaction. Pure product. Disadvantages: Uses finite resources, e.g crude oil cane. Uses high temp and pressure therefore high energy input.Advantages: Fast rate of reaction. Pure product. Uses low temp and pressure therefore low energy input Disadvantages: Uses finite resources, e.g crude oil cane. Uses batch process which is inefficient.Question 9 of 14 Loading... 10. What type of reaction is the complete combustion of ethanol?OxidationAdditionDecompositionSubstitutionQuestion 10 of 14 Loading... 11. Which ester is produced when ethanol and ethanoic acid react in the presence of an acid catalyst?Methyl ethanoideEthyl ethanoideEthyl ethanoateMethyl ethanoateQuestion 11 of 14 Loading... 12. In the production of ethanol by fermentation, why is the process done at an optimal temperature of 30⁰C?So the yeast is warm enough to perform anaerobic respiration, but below the temperature at which the zymase enzyme would denatureSo that the yeast is warm enough to catalyse the reaction between oxygen and sugar to produce ethanolTo prevent the reaction happening too quickly, leading to a dangerous build up of ethanolTo increase the life span of the yeast, so the production doesn\'t have to be stopped often to replace themQuestion 12 of 14 Loading... 13.
