Rates of Reaction Problem

A particular reaction was found to depend on the concentration of the hydroxyl ion [OH-]. The initial rates varied as a function of initial pOH as follows:

pOH 2.699 2.398 2.097
initial rate 1.600e-2 6.400e-2 2.560e-1
(M/s)

Predict the initial reaction rate when pOH is 2.155.

Solution Preview

Rate = k * [OH]x

pOH = 2.699 --> [OH] = 2 *10-3

pOH = 2.398 --> [OH] = 4*10-3

Rate1 k * [OH]1x
--------- = ...

Solution Summary

Calculations and answers are determined using Rate = k * [OH]x.
