Canceling out the constants and taking the natural log of both sides gives us this:
<span>Ea1/T1=Ea2/T2 </span>
<span>Ea1=75kJ </span>
<span>T1=298K </span>
<span>Ea2=49kJ </span>
<span>T2=? </span>
<span>So now, </span>
<span>T2= Ea*T1/Ea = 75*298/49 </span>
<span>Your answer should be 456.12 = 456K!
