Solution: The reaction between ethyl bromide (C2H5Br) and hydroxide ion (OH -) in ethyl alcohol at 330 K is first order each in ethyl bromide and hydroxide ion. C2H5Br(alc) + OH -(alc) → C2H5OH(I) + Br -(alc) How would the rate of ethyl bromide change if the solution were diluted by adding an equal volume of pure ethyl alcohol to the solution.   a) no change b) decrease by a factor of four c) increase by a factor of four d) increase by a factor of two e) decrease by a factor of two

Problem

The reaction between ethyl bromide (C2H5Br) and hydroxide ion (OH -) in ethyl alcohol at 330 K is first order each in ethyl bromide and hydroxide ion.

C2H5Br(alc) + OH -(alc) → C2H5OH(I) + Br -(alc)

How would the rate of ethyl bromide change if the solution were diluted by adding an equal volume of pure ethyl alcohol to the solution.

 

a) no change

b) decrease by a factor of four

c) increase by a factor of four

d) increase by a factor of two

e) decrease by a factor of two
