Question:medium

For the reaction \[ N_2 + O_2 \rightleftharpoons 2NO \] the equilibrium concentrations are given as \[ [N_2]=0.5\,M,\qquad [O_2]=0.7\,M,\qquad [NO]=0.4\,M \] Calculate the value of \(K_c\).

Show Hint

Always write the balanced chemical equation first and then construct the equilibrium constant expression using stoichiometric coefficients as powers.
