Chapter 6, Problem 3Q

A kinetic study yielded the following reaction rate data:

Initial Concentrations

Experiment Number	[HO−]	[R─Br]	Initial Rate of Disappearance of R─BrR─Br and Formation of R─OH
1	0.50	0.50	1.00
2	0.50	0.25	0.50
3	0.25	0.25	0.25

Which of the following statements best describe this reaction?

(a) The reaction is second order.

(b) The reaction is first order.

(c) The reaction is S_N1.

(d) Increasing the concentration of HO⁻ has no effect on the rate.

(e) More than one of the above.
