Transcribed Image Text:Chemistry
While ethanol (CH₂CH₂OH) is produced naturally by fermentation, e.g. in beer- and wine-making, industrially it is synthesized by reacting ethylene
(CH₂CH₂) with water vapor at elevated temperatures.
A chemical engineer studying this reaction fills a 200. mL flask with 4.0 atm of ethylene gas and 1.4 atm of water vapor. When the mixture has come to
equilibrium she determines that it contains 3.1 atm of ethylene gas and 0.50 atm of water vapor.
The engineer then adds another 2.0 atm of ethylene, and allows the mixture to come to equilibrium again. Calculate the pressure of ethanol after equilibrium is
reached the second time. Round your answer to 2 significant digits.
