Question

The Kinetics of decomposition of N2O5 was obeserved:

[ N2O5]                     Time

  2.50 atm                 0 sec

  2.22                       200

  1.96                       400

  1.73                       600

  1.53                       800

Do Data indicate a first order reaction or second order reaction?
