for this q, i may be incorrect but are none of the given options correct? X > Z, Z > Y and X > Y. Therefore, X> Z > Y in terms of reactivity.

also can anyone explain to me how heterogenous catalysts work and also explain the concept of bond atomisation and how it relates to bond enthalpies. yes ive tried searching and im still confused.
