Chapter 14, Problem 14.77QP

When heated at high temperatures, iodine vapor dissociates as follows:

${\text{I}}_2(g)\stackrel{}{\rightleftharpoons }2\text{I(}g\text{)}$

In one experiment, a chemist finds that when 0.054 mole of I₂ was placed in a flask of volume 0.48 L at 587 K, the degree of dissociation (that is, the fraction of I₂ dissociated) was 0.0252. Calculate K_c and K_P for the reaction at this temperature.
