In \( \text{F}^- \), Ne, and \( \text{Na}^+ \), all have \( 1s^2, 2s^2, 2p^6 \) configuration. They differ in size due to differences in nuclear charge, affecting their pull on electrons.
For the reaction, \[ H_2(g) + I_2(g) \rightleftharpoons 2HI(g) \] Attainment of equilibrium is predicted correctly by:
