18 14.26) The reaction between ethyl bromide and hydroxide ion in ethyl alcohol at 330 K is: C 2 H 5 Br (alc) + OH (alc) v C 2 H 5 OH ( R ) + Br (alc) The reaction is found to be first-order in each of the reactants, C 2 H 5 : r = k [C 2 H 5 Br] [OH ] When [C 2 H 5 Br] = 0.0477 M and [OH ] = 0.100 M, the rate of disappearance of C 2 H 5 Br is 1.7 x 10 7 M/s, ) [C 2 H 5 Br]/ ) t = 1.7 x 10 7 M/s Since the coefficient of C 2 H 5 Br is 1 the rate law for THE rate of rxn is the same as that given above and THE rate of rxn is the same are the rate of disapp. of C 2 H 5 Br. a) & b) What is the value of the rate constant? Solve the rate law for k. r 1.7 x 10 7 M/s k = -------------------- = ---------------------------- [C 2 H 5 Br][OH ] (0.0477 M) (0.100 M)
