For the reaction
$CO(g) + \frac{1}{2}{O_2}(g) \leftrightarrow C{O_2}(g)$
$\Delta {n_g} = 1 - \left( {1 + \frac{1}{2}} \right) = - \frac{1}{2}$
$\therefore \,{K_P} = \frac{{{K_C}}}{{\sqrt {RT} }};\,\frac{{{K_P}}}{{{K_C}}} = \frac{1}{{\sqrt {RT} }}$
(અહીં : $SrCO_{3(s)} \rightleftharpoons SrO_{(s)}+ CO_{2(g)} \,, K_p=1.6\,atm$)
