While ethanol  CH3CH2OH  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  1.2atm  of ethylene gas and  1.3atm  of water vapor. When the mixture has come to equilibrium she determines that it contains  0.25atm  of ethylene gas and  0.35atm  of water vapor.   The engineer then adds another  0.30atm  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.

Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.
