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.

The Born-Haber process is, N2 (g) + 3 H2 (g) = 2 NH3 (g) has an equilibrium position when [N2] = 12.9 M, [H2] = 0.600 M and (NH3] =0.500 M. (a) What is the value of K? (b) If [N2] = 2.30 M, [H2] = 0.500 M and (NH3] =0.150 M, then are these concentrations at an equilibrium position? If not, then in which direction will a shift bring about equilibrium?
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 1.5 L flask with 4.8 atm of ethylene gas and 3.9 atm of water vapor. When the mixture has come to equilibrium she determines that it contains 3.1 atm of ethylene gas and 2.2 atm of water vapor. The engineer then adds another 1.2 atm of ethylene, and allows the mixture to come to equilibrium again. Calculate the pressure of ethanol after equilibrium is reached the second time.
