Predict how the addition of hydrogen gas would affect the initial rate of the reaction below, and explain your prediction.

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

The rate of the forward reaction would increase,
Normal Chem explanation: because one of the reactants is now more abundant.
AP chem explanation: Le Chatlier's principle, the reaction works to relieve the new stress, shifting equilibrium to the right

Explanation:

According to Le Chaltelier's principle, when a system is in chemical equilibrium and there occurs any change in concentration, temperature, or pressure then the equilibrium will shift in the direction which is opposing the change.

For example, when concentration of hydrogen gas is increased for the reaction [tex]H_{g} + I_{2}(g) \rightarrow 2HI[/tex] then equilibrium will shift of the right hand side.

That is, formation of product will become faster on increasing the concentration of hydrogen gas.
