A student ran the following reaction in the laboratory at 675 K: H2(g) + I2(g) 2HI(g) When she introduced 0.226 moles of H2(g) and 0.248 moles of I2(g) into a 1.00 liter container, she found the equilibrium concentration of I2(g) to be 6.11×10-2 M. Calculate the equilibrium constant, Kc, she obtained for this reaction.

A student ran the following reaction in the laboratory at 675 K:

H2(g) + I2(g) 2HI(g)

When she introduced 0.226 moles of H2(g) and 0.248 moles of I2(g) into a 1.00 liter container, she found the equilibrium concentration of I2(g) to be 6.11×10-2 M.

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