Solved: Ethene (C2H4) can be halogenated by the reaction: where X2 can be Cl2, Br2, or

QUESTION:

Ethene (\(\mathrm{C}_{2} \mathrm{H}_{4}\)) can be halogenated by the reaction:

\(\mathrm{C}_{2} \mathrm{H}_{4}(g)+X_{2}(g) \rightleftharpoons \mathrm{C}_{2} \mathrm{H}_{4} X_{2}(g)\)

where \(\mathrm{X}_{2}\) can be \(\mathrm{Cl}_{2}\), \(\mathrm{Br}_{2}\), or \(\mathrm{I}_{2}\). Examine the figures representing equilibrium concentrations of this reaction at the same temperature for the three different halogens. Rank the equilibrium constants for these three reactions from largest to smallest.
