(40 marks) Question 1 An ethanol dehydrogenation reaction is carried out with the feed entering at 300 °c. The feed containing 90.0 mole % ethanol (C2H5OH) with the balance acetaldehyde(CH3CHO) enters a reactor at a rate of 150 mol/s. Heat is transferred to the reactor to keep the temperature from dropping too much and thereby decreasing the reaction rate to an unacceptably low...
