Suppose we start with 0.0250 mol of N2O5 (g) in a volume of 2.0 L. The first order rate constant for the decomposition of N2O5, N2O5 (g) ---> 2JO2 (g) + O2 (g), at 70 degrees Celsius is 6.82 x10^-3 s^-1.
1. Determine the numbers of moles of N2O5 will remain after the 2.5min?
2. Determine the numbers of minutes will it take for the quantity of N2O5 to drop to 0.020mol?
3. Determine the half life of N2O5 and 70 degrees Celsius?
