Which outcome inhibits iron-56 formation during silicon burning?

A)High neutrino emission rates
B)Insufficient electron degeneracy pressure
C)Exceeding the Chandrasekhar limit
D)Increased overall binding energy

💡 Explanation

Increased overall neutron excess inhibits iron-56 formation because the increased coulomb repulsion raises the endpoint of statistical equilibrium with increasingly tighter binding energies, therefore creating heavier, larger nuclei, rather than only fusing to iron-56 alone.
