If (delta)H for the contact process were +98 KJ/mol instead of -98 KJ/mol, which of the following conditions might it be sensible to employ? Give reasons for any differences between these conditions and those which are actually used in the contact process.
X=1000 K, 2 atm, no catalyst.
Y= 400 K, 10 atm, V2O5 catalyst
Z= 1000 K, 10 atm, V2O5 catalyst
Use Le Chatelier’s Principle to suggest the conditions of temperature and pressure which would ensure a good yield of synthesis gas. (4 marks)
Ethanol may be manufactured by the hydration of ethene. State an explain the effect on the position of equilibrium in this reaction of : i) increasing the temperature (2 marks), ii) increasing the pressure (2 marks), iii) using a catalyst (2 marks).
