Consider the reaction \( \mathrm{N}_{2} \mathrm{O}_{4}(\mathrm{~g}) \rightleftharpoons 2 \mathrm{NO}_{2}(\mathrm{~g}) \)…

Consider the reaction \( \mathrm{N}_{2} \mathrm{O}_{4}(\mathrm{~g}) \rightleftharpoons 2 \mathrm{NO}_{2}(\mathrm{~g}) \).

The temperature at which \( \mathrm{K}_{\mathrm{C}}=20.4 \) and \( \mathrm{K}_{\mathrm{P}}=600.0 \mathrm{~K} \). (Round off to the nearest integer) (Assume all gases are ideal and \( \mathrm{R}=0.0831 \mathrm{~L} \mathrm{bar} \mathrm{K}^{-1} \mathrm{~mol}^{-1} \))
