Question

8. Ethanol (C2H5OH) is synthesized for industrial use by the following reaction, carried out at very high pressure. C2H4 (g) + H2O(g) - C2H5OH (1) What is the maximum amount, in kg. of ethanol that can be produced when 1.45 kg of ethylene (C2H4) and 0.0433 kg of steam are placed into the reaction vessel? How many kg of excess reactant will be left over?

Answer 1

Maximum yield of ethanol = 0.111kg

Limiting reagent is water/steam and excess reagent is ethylene

Left over excess reagent i.e., ethylene = 1.38kg
