Question: Nitrogen and hydrogen react to form ammonia, like this: N2 (g) +3H2 (g) 2NH3 (g) Imagine 119.mmol of NH3 are added to an empty flask,

Nitrogen and hydrogen react to form ammonia, like this:

N2(g) +3H2(g)2NH3(g)

Imagine 119.mmol of NH3 are added to an empty flask, and then answer the following questions.

What is the rate of the reverse reaction before any NH₃ has been added to the flask?	Zero.
	Greater than zero, but less than the rate of the forward reaction.
	Greater than zero, and equal to the rate of the forward reaction.
	Greater than zero, and greater than the rate of the forward reaction.
What is the rate of the reverse reaction just after the NH₃ has been added to the flask?	Zero.
	Greater than zero, but less than the rate of the forward reaction.
	Greater than zero, and equal to the rate of the forward reaction.
	Greater than zero, and greater than the rate of the forward reaction.
What is the rate of the reverse reaction at equilibrium?	Zero.
	Greater than zero, but less than the rate of the forward reaction.
	Greater than zero, and equal to the rate of the forward reaction.
	Greater than zero, and greater than the rate of the forward reaction.
How much NH₃ is in the flask at equilibrium?	None.
	Some, but less than 119. mmol.
	119. mmol.
	More than 119. mmol.
