a 0.5 mol of N2O2 in a 1liter beaker, decompose to NO2, process is first order with rate constant 4500/s at 25 degreesC.
How many molecules of N2O4 will remain after decomposing for 1.2 minutes?
show a sol'n plz, tnx

d[N2O4]/dt=k*[N2O4]
d[N2O4]/[N2O4]=k dt
Integrate from 0 to 72 seconds
ln ([N2O4]/.5M)=4500/sec* (72s)
Solve from there, do the logrithms correctly
Then multiply by Avagradro's number to get #molecules from moles.

you need to give the equation for the first order rxn so that I can plug in the numbers
its not that hard you just need to put numbers into an equation and solve
