A chemist conducted a study on ammonia NH3(g) into hydrogen gas and nitrogen gas. This reaction is represented by the following balanced equation:

2 NH3(g) à N2(g) + 3 H2(g)

The rate of consumption of ammonia gas was determined to be 0.0036 mol/(Ls). What is the rate of formation for hydrogen gas in the experiment?
