Ethene (C2H4) can be halogenated by the following reaction:
C2H4(g)+X2(g)⇌C2H4X2(g)
where X2 can be Cl2 (green), Br2 (brown), or I2 (purple). Examine the three figures below representing equilibrium concentrations in this reaction at the same temperature for the three different halogens. Rank the equilibrium constants for these three reactions from largest to smallest.
Rank from largest to smallest. To rank items as equivalent, overlap them.
