A student ran the following reaction in the laboratory at 689 K
H2(g) + I2(g) 2 HI(g)

When she introduced 0.218 moles of H2(g) and 0.244 moles of I2(g) into a 1.00 Liter container, she found the equilibrium concentration of I2(g) to be 6.28E-2 M.

Calculate the equilibrium constant, Kc, she obtained for this reaction?
