For the reaction $2{\mathrm{N}}_2{\mathrm{O}}_5\left(\mathrm{g}\right)\rightleftharpoons 4{\mathrm{NO}}_2\left(\mathrm{g}\right)+{\mathrm{O}}_2\left(\mathrm{g}\right)$, which of the following is true at 300°C?

$\mathrm{\Delta }{\nu }_{\mathrm{g}}=3;K_p=K_c(RT{)}^3\Rightarrow K_p>K_c$ because $RT>1$.

The equilibrium constant, abbreviated as k, is a quantity that aids in describing the correlation between the quantity of reactants and products present at equilibrium for a reversible chemical reaction at a specific temperature.
