for cracking : the temp is 300 degree Celsius and the catalyst used is Alo3
oh and there is also Hydration : u add steam to ethene at abt 700 degree celcius , with the presence of a phosphoric catalyst and at 60 atmospheric pressure
addition ploy : 200 atmospheric pressure & 150 degree Celsius
hope i didn't forget anythin ....sure mate ;)

Um, in my book for cracking its 540*C :-\ and yeah typo Al2O3 ;)
