What is the value of K in the equilibrium reaction of acetic acid: HC₂H₃O₂ ⇌ H⁺ + C₂H₃O₂^-, if [H⁺] = 0.20 M and [HC₂H₃O₂] = 0.30 M?

Question

Quizplus · Accepted Answer

The equilibrium constant expression for the given reaction is:K = [H+][C₂H₃O₂^-]/[HC₂H₃O₂]Substituting the given concentrations into the expression, we get:K = (0.20 M)(0.20 M)/(0.30 M) = 0.13 M
