For the reaction h2(g) + i2(g) 2hi(g), kc = 50.2 at 445ºc. If [h2] = [i2] = [hi] = 1.75  10-3 m at 445ºc, which one of these statements is true?

a. The system is at equilibrium, thus no concentration changes will occur.
b. The concentrations of hi and i2 will increase as the system approaches equilibrium.
c. the concentration of hi will increase as the system approaches equilibrium.d. The concentrations of h2 and hi will fall as the system moves toward equilibrium.
e. The concentrations of h2 and i2 will increase as the system approaches equilibrium.
