In which of the following equilibria, \({K}_{p}\) and \({K}_{c}\) are not equal? [NEET 2024]

\(2{\mathrm{BrCl}}_{(\mathrm{g})}⇌{\mathrm{Br}}_{2(\mathrm{g})}+{\mathrm{Cl}}_{2(\mathrm{g})}\)

\({\mathrm{PCl}}_{5(\mathrm{g})}⇌{\mathrm{PCl}}_{3(\mathrm{g})}+{\mathrm{Cl}}_{2(\mathrm{g})}\)

\({\mathrm{H}}_{2(\mathrm{g})}+{\mathrm{I}}_{2(\mathrm{g})}⇌2{\mathrm{HI}}_{(\mathrm{g})}\)

\({\mathrm{CO}}_{(\mathrm{g})}+{\mathrm{H}}_{2}{\mathrm{O}}_{(\mathrm{g})}⇌{\mathrm{CO}}_{2(\mathrm{g})}+{\mathrm{H}}_{2(\mathrm{g})}\)
