A blog covering and explaining the Edexcel IGCSE Chemistry specification for the 2016 summer exams. If you are doing just double science, you do not need to learn the stuff for paper two, if you are doing triple you will need to learn all (GOOD LUCK!) I have separated the papers to make files easier to find. Hope it helps :)
3.9 describe the manufacture of ethanol by passing ethene and steam over a phosphoric acid catalyst at a temperature of about 300ºC and a pressure of about 60-70 atm
Ethene will react with steam to produce ethanol. This reaction will take place at 300ºC with a pressure of 60-70 atm. This process is very slow, so a catalyst of phosphoric acid is used. NOTE: atm stands for atmospheres
