What would be the concentration of dinitrogen pentoxide after 6.00 X 10(2) seconds and how long would it take for the concentration of N2O2 to decrease to 10.0% of its initial value in the following equation...
N2O5 to NO2 and O2
initial concentration is 1.65 X 102mol/L
rate constant is 4.80 X 104/s
time is 825s
According to my book, the answer is 1.24 X 102 mol/L and t= 4.80 X 10 (3)s
I can't figure out how to solve t=4.80 X 10 (3)s
Do I set up like this...
ln (0.00124/0.0165)=4.80 X 104 X t?

What are you doing? I worked this for you last night (at least part a). I described how to do the second part. Did you read that? You aren't approaching it in the manner I told you it could be worked.
