1. In this activity, we will be exploring the relationship between the amount of a radioactive substance and the rate of decay. There are many forms of radioactive decay. For this activity we will be using beta (B) decay, when a neutron decays into an electron and proton, and gamma (7) decay, when an atom emits energy through a gamma photon.

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 =
