Question

In the esterification C 2 H 5 O H l + C H 3 C O O H l ⇌ C H 3 C O O C 2 H 5 l + H 2 O l an equimolar mixture of alcohol and acid taken initially yields under equilibrium, the water with mole fraction = 0.333. The equilibrium constant is.,

MARKS App · Accepted Answer

As alcohol and acid are equimolar so the initial concentration would also be same. Suppose the initial concentration is 'C'. x C - x + C - x + x + x = 0.33 = 1 3 3 x = 2 C x = 2 C 3 K c = 2 C 3 × 2 C 3 C - 2 C 3 × C - 2 C 3 = 4
