<p>Hey Dr. Pounds,</p>
<p>On Chapter 14 #44, it is asking us to find Temperature 2. I
thought I knew how to do it, but I think my algebra is messing
up somewhere. On your solutions, you got 644 K, but I keep
getting a tiny number. This is my work...</p>
<p> </p>
<p>ln(k2/k1)=(Ea/R)[(1/T1)-(1/T2)]</p>
<p> </p>
<p>ln(8.80E-4/4.60E-4)= (104000J/8.314 J)[(1/623)-(1/T2)]</p>
<p> </p>
<p>.648695418= 12509.02093[(1/623)-(1/T2)]</p>
<p> </p>
<p>5.18582E-5= [(1/623)-(1/T2)]</p>
<p> </p>
<p>.0015532782= (1/T2)</p>
<p> </p>
<p>THIS IS WHERE I AM GETTING LOST. I am not too sure if I did
my math wrong or did the whole problem wrong. Sorry this was
so lengthy!
</p>
<p> </p>
<p> </p>
<p>Thank you!</p>
