One of the "Points to Consider" is:<br>
<br>
"Determine the activation energy calculated for this reaction, with
proper units.<br>
Does this number make sense? What ballpark range of Ea do you
expect?"<br>
<br>
I keep getting the following question concerning this,<br>
<br>
"How do I know if my Ea is reasonable? What ballpark range of Ea
should I expect?<br>
Is there something I can compare it to?"<br>
<br>
<b>Here's the answer I've been giving:</b><br>
<br>
Look in the textbook in section 14.5 (temperature and rate). There
are values given<br>
there (particularly in the Sample Exercises). Also, look at the
homework problems<br>
at the end of the chapter. You can make reference to these.<br>
<br>
Finally, I spoke about this in class and gave an idea of the sizes
of Ea values and how<br>
catalysts affect Ea values (also discussed in the book).<br>
