The reaction between ethyl bromide (C2H5Br) and hydroxide ion in ethyl alcohol at 330 K, C2H5Br(alc) + OHˉ (alc) --→ C2H5OH(I) + Brˉ(aIc), is first order each in ethyl bromide and hydroxide ion. When [C2H5Br] is 0.0477 M and [OHˉ] is 0.100 M, the rate of disappearance of ethyl bromide is 1.7 × 10-7 M/s.
(a) What is the value of the rate constant?
(b) What are the units of the rate constant?
