Acetic acid (CH 3 COOH) reacts with water to form the acetate ion and the hydronium ion: CH 3 COOH(aq)+H 2 O(l) leftrightarrow CH 3 COO^ - (aq)+H 3 O^ + (aq) At equilibriumthe concentration of CH 3 COOH is 2.0 * 10 ^ - 1 * M the concentration of CH 3 COO^ - 1.9 * 10 ^ - 3 * M and the concentration of H 3 O^ + is 1.9 * 10 ^ - 3 * M What is the value of K eq for this reaction? 1.8 * 10 ^ - 5 5.5 * 10 ^ 4 9.5 * 10 ^ - 3 1.1 * 10 ^ 2
