<p>For lab this week we are doing the Gaseous Equilibrium Lab.
There are two things shown in the video and described in the
procedures that you are not required to do.</p>
<p>1. You will not have to build the gas generator and collect the
gas. Each lab group will be given a blank and a spec tube
containing a mixture of NO2 and N2O4.</p>
<p>2. You will not have to do the timing study -- where you record
the absorbance as a function of time.</p>
<p>As such you will not need to include the description of these
things in your lab notebook procedures.</p>
<p><br>
</p>
<p>You will do exactly three experiments.</p>
<p>1. Measure the room temperature absorbance</p>
<p>2. Measure the absorbance below room temperature</p>
<p>3. Measure the absorbance above room temperature</p>
<p>It is a much safer (and simpler) lab than what we did in the
past. The notebook prep is also simpler. The writeup is, however,
more difficult. We will talk about that later this week</p>
