Dinitrogen tetraoxide a colorless gas exists in equilibrium

Question

Dinitrogen tetraoxide, a colorless gas, exists in equilibrium with nitrogen dioxide, a reddish brown gas.

One way to represent this equilibrium is:

N₂O₄(g) <---->2NO₂(g)

Indicate whether each of the following statements is true, T, or false, F. 

AT EQUILIBRIUM we can say that:

1. The concentration of NO₂ is equal to the concentration of N₂O₄.________(true or false)

2. The rate of the dissociation of N₂O₄ is equal to the rate of formation of N₂O₄. _______(true or false)

3. The rate constant for the forward reaction is equal to the rate constant of the reverse reaction._______(true of false)

4. The concentration of NO₂ divided by the concentration of N₂O₄ is equal to a constant.________(true or false)
