Based on the activation energies and frequency factors, rank the
following reactions from fastest to slowest reaction rate, assuming
they are all at the same temperature and that each starts with the
same initial concentration.
Rank from fastest to slowest reaction rate. To rank items as
equivalent, overlap them.
Fraction of molecules
The exponential term in the Arrhenius equation is equal to the
fraction of molecules, f, with kinetic energy greater than or equal
to the activation energy:
f=e−Ea/(R⋅T)
