Ethanol (C2H5OH) is synthesized for industrial use by the following reaction, carried out at very high pressure.

Question

C2H4(g) + H2O(g) → C2H5OH(l)

What is the maximum amount, in kg, of ethanol that can be produced when 1.65 kg of ethylene (C2H4) and 0.0610 kg of steam are placed into the reaction vessel?

Answer 1

Get the Limiting Reactant of your reaction,

so get the Molar Mass (MM) of C2H4 and H2O from your periodic table

then

1650 g / MM of C2H4 = __ mol
61 g / MM of H2O = __ mol

the least amount of mol will be your Limiting Reactant.

You use the LR to find the max amount of C2H5OH you will get from your reaction

so

LR in mol * MM of C2H5OH = ___ g

divide answer to get your max amt. in kg

Answer 2

*divide answer by 1000 to get max amt in kg

Answer 3

thanks!
