Compare the two equlibria involving SO_{2} (g) and their two corresponding equilibrium constants.
SO_{2}(g) + 1/2O_{2}(g) ? SO_{3} (g) K_{1}
2SO_3(g) ? 2SO_2(g) + O_2 (g) K_{2}
Which of these expressions correctly relates K_{1} to K_{2} ?
K_{2} = 1 / (K_{1} ^ 2)
K 2 ^ 2 =K 1
K_{2} = 1 / K_{1}
K_{2} = K_{1} ^ 2
K_{2} = K_{1}
