Describe the changes in equilibrium of ethanol production from ethene and water (enthalpy of reaction is ∆H = - 46 kJ/mol) when: (a) a high pressure is applied; (b) ethanol concentration is increased; (c) temperature is increased; (d) a catalyst is used.

The equation for the reaction (would be given for this type of question but I ran out of space): C₂H₄ (g) + H₂O (g) ⇌ C₂H₅OH (g) ∆H = - 46 kJ/molQues...

Describe how you could distinguish between ethanol, ethanoic acid, ethyl bromide and 2-methylpropan-1-ol.

First, you should add sodium hydrogen carbonate to all three compounds. Ethanoic acid will react with this to release a gas which will turn limewater cloudy.
Second, you should add acidified potassi...
