equilibrium constant Kc for the reaction. In this experiment‚ I will study the equilibrium properties of the reaction between ethanoic acid‚ otherwise known as acetic acid (CH3COOH) and water (H2O): CH3COOH(aq) + H2O(l) CH3COO-(aq) + H3O+(aq) When solutions containing ethanoic acid and water are mixed‚ they react to some extent‚ forming CH3COO- and H3O+. As a result of the reaction‚ the equilibrium amounts of CH3COOH and H2O will be less; for every mole of CH3COO- formed‚ one mole of CH3COOH and one

Circle C1 has center O and radius r. Circle C2 has center P and radius OP. Let A be one of the points of intersection of C1 and C2. Circle C3 has center A and radius r (therefore circles C1 and C3 are the same size). The point P’ (written P prime) is the intersection of C3 with OP. This is shown in
