(a) Use Wade’s rules to rationalize the fact that in [Pd@Bi|0]4+, the Bi atoms are arranged in a pentagonal antiprism. How is this structure related to that of [Pd@Pb|2]2 ?


(b)  At 298 K, ammonium perchlorate decomposes according to the equation:

4NH4C1O4(s) — 2Cl2(g)

+ 2N2O(g) + 3O2(g) T" 8H2O(1)

Determine ArC/0(298 K) for this decomposition if AfG°(298 It) of N2O(g), H2O(I) and NH4C1O4(s) are + 1O4, —237 and -89 kJ mol-1. What part does entropy play in the reaction?
