Calculate the rate constant, k, by using Equation 3 (k'=k[OH]^1). Keep in mind, the NaOH solution was diluted by 50% at the start of the experiment. Write a final generic rate law using Equation 1 (k[OH]^x[CV]^y) using the experimental determined values for k, and y. Find the average for CV (Crystal Violet) order (y), pseudo rate constant (k'=3.1x10^-8 Ms^-1), and the rate constant (k). The generic rate law is Rate = k(actual value with correct units)[CV]^(order for cv)[OH]^1. Section #:...
