WebAt equilibrium, the value of the equilibrium constant is equal to the value of the reaction quotient. At equilibrium, (2.3.7) K e q = Q c = [ N 2 O 4] [ NO 2] 2 = 0.042 0.016 2 = 1.6 × 10 2. The equilibrium constant is 1.6 × 10 2. Note that dimensional analysis would suggest the unit for this K e q value should be M−1. WebFor example, bismuth chloride reacts with water in a reversible reaction: BiCl 3 (aq) + H 2 O(l) ⇌ BiOCl(s) + 2HCl(aq) The concentration of hydrochloric acid can be increased by adding more ...
WebJan 26, 2024 · The reaction may be said to be "complete" or "quantitative." If the value for the equilibrium constant is small, then the equilibrium favors the reaction to the left, and there are more reactants than products. If the value of K c approaches zero, the reaction may be considered not to occur.
