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)
