According to Le Chatelier’s principle, which direction will the equilibrium shift if the concentration of the I2 is increased according to the following reaction at equilibrium?

2Ce(IO3)4(aq) + 24 H2C2O4(aq) ↔ Ce2(C2O4)3(aq) + 4I2(aq) + 42 CO2(g) + 24 H2O(l)

right
left
no change

The equilibrium will shift to the left to decrease the concentration of I2.
