# DarianaCalculating an equilibrium composition after a prior equil..While ethanol (CH, CH,OH) is produced naturally by fermentation, e.g. in beer- and wine-making, industrially it is synthesized by reacting ethylene(CH, CH,) with water vapor at elevated temperatures.A chemical engineer studying this reaction fills a 500. mL flask with 3.1 atm of ethylene gas and 4.4 atm of water vapor. When the mixture has cometo equilibrium she determines that it contains 2.0 atm of ethylene gas and 3.3 atm of water vapor.oloThe engineer then adds another 2.2 atm of water, and allows the mixture to come to equilibrium again. Calculate the pressure of ethanol afterequilibrium is reached the second time. Round your answer to 2 significant digits.ArI| atmOx10

Step 1

For the given reaction, the equation for equilibrium constant can be written as above.

Step 2

As the reaction proceeds, it attains equilibrium and hence the equilibrium pressure can be determined using ICE table.

At equilibrium,

Pethylene = (3.1 – x)

2.0 = 3.1 – x

X = 3.1 – 2.0

X = 1.1

Pethanol = 1.1 atm

PH2O = 3.3 atm

Step 3
