H2 Chemistry 9 - Chemical Equilibria: Kc Calculation and Le Chatelier's Principle

What you will learn

• Esterification of ethanol with ethanoic acid to ester + water; equilibrium concentrations 0.33, 0.33, 0.67, 0.67 mol/dm^3.
• Kc = (0.67)(0.67) / (0.33)(0.33) = 4.1, no units; water is included because all species are in the liquid phase.
• Adding ethanol shifts equilibrium right (more ester); Kc itself does not change because it depends only on temperature.
