The order of first ionization enthalpy (\( I_{E_1} \)) for these elements is:
\(\text{Al} < \text{Si} < \text{C} < \text{N}\)
Thus, nitrogen (\( \text{N} \)) has the highest first ionization enthalpy among the given options.
The Correct Answer is: N
For the reaction, $H_2(g) + I_2(g) \rightleftharpoons 2HI(g)$
Attainment of equilibrium is predicted correctly by:
