The decomposition of N205 to NO2 and 02 is first order, with a rate constant of 4.80 x 10-4/s at 45°C. If the initial concentration of N205 is 4.85x10-2 mol/L, what is the concentration of N205 after 460 s? How long would it take for the concentration of N205 to decrease to 1.00 x 10-2 mol/L from an initial concentration of 4.85x10-2 mol/L?
