For the decomposition of hydrogen peroxide in dilute sodium hydroxide at 20

For the decomposition of hydrogen peroxide in dilute sodium hydroxide at 20 degree C the following data have been obtained: The average rate of disappearance of H2O2 over the time period from t = 0 min to t = 8.62 min is_______ M min^-1. For the gas phase decomposition of dinitrogen pentoxide at 335 K the following data have been obtained: The average rate of disappearance of N2O5 over the time period from t = 240 s to t = 360 s is _______ M s^-1.

Explanation / Answer

Average rate of diapperance =(8.88-5.03)/8.62 X 10^-2 = 4.46 X 10-3 M ./min

averge rate =((2.4 - 1.38 )/120 ) X 10 ^-2 = 8.5 X 10-5 M/ s
