CH3-COOH + C6H5-CH2-OH ⇒ CH3COOCH2-C6H5 + H2O
initial : a moli b moli
au reactionat: x x
la echilibru: (a-x) (b-x) x x
n ester = x = 150/150 = 1 mol
a - x = 2 a = 3 moli
a) x = 80% din b ⇒ b = 100/80 = 1,25 moli
b) x = 1mol
c) K = x² /[a-x)(b-x) = 1/(2·0,25) = 2
d) a - x = 2 a = 3 moli
e) Cu = 1·100/3 = 33,33%
