For the reaction NO2 --> NO + O and given this information:
a graph of In[NO2] vs time is a curve
a graph of 1/[NO2) vs time is a straight line
a graph of [NO2] vs time is a curve.
what order is the reaction?

The bond energy for the van der waals bond between two helium atoms is 7.9×10−4ev. assuming that the average kinetic energy of a helium atom is (3/2)kbt, at what temperature is the average kinetic energy equal to the bond energy between two helium atoms
