Buffer Distance
(0)/(1)
point (graded) The "buffer distance" is defined as the difference between the equilibrium distance
r_(e)
in an ionic compound XY, and the electron jump distance at which the harpoon mechanism occurs,
r^(*)
. Calculate the buffer distance, in angstroms, in a hypothetical ionic compound XY , consisting of
x^(+)
and
Y^(-)
ions, using the
r_(e)
from the previous problemb(which is 2.23 angstroms) and the following data: Ionization Energy of X:
IE=439.3(kJ)/(mol)
Electron Affinity of Y: EA
=317.1(kJ)/(mol)
Your answer is outside the acceptable bounds. You may have made a calculation or rounding error. ? Hint (1 of 1): Buffer distance is
r^(*)-r_(e)
