Question

An early use of relaxation methods by Manfred Eigen found that this reaction takes ten hours in one direction but only picoseconds in reverse. The “rational” equilibrium constant for this reaction is 1.74 magnitudes too small (10[1])in some organic chemistry textbooks due to a convention mistakenly introduced by Johannes (10[1])Brønsted. (-5[1])The spatial separation of this reaction’s products is facilitated by solvent clusters that form a “wire” between them. The Charlot equation explicitly considers the effects of this reaction, (10[1])which is ignored by the Henderson–Hasselbalch (10[1])equation. (10[1]-5[1])Using (10[1])an (10[1])activity (10[1])of 1 instead of a concentration of 55 (-5[1])M allows a value of 10 (-5[1])to the negative 14 (10[2])to be assigned to this reaction’s (10[1])equilibrium (10[1])constant, (10[1])K-sub-w. (-5[1])For 10 points, (10[1])name (10[1])this reaction that ensures water has a non-zero concentration of both hydronium and hydroxide. ■END■ (10[2]0[4])
