Explanation:
Ethanol can be dehydrated to give ethene by heating it with an excess of concentrated sulphuric acid at about 170°C. Concentrated phosphoric(V) acid, H3PO4, can be used instead. The acids aren't written into the equation because they serve as catalysts.
Propanol is an alcohol. Propanoic acid is a carboxylic acid. Propanol is converted into propanoic acid by an oxidation reaction, where catalysts such as potassium dichromate and potassium permanganate are used.
