Dinitrogen tetraoxide is a colorless gas at room temperature. It can dissociate into nitrogen dioxide, which is a reddish brown gas.

N₂O4(9) 2 NO₂(g)

Three experiments were run starting with different initial amounts of N₂O(g) (N₂O4lo in the table). The systems were allowed to reach

equilibrium and the concentrations for each gas were measured (in units of moles/Liter).

For each of the boxes below, calculate the ratios indicated by the column heading. This will show the mathematical relationship that exists.

between the concentrations of NO and N₂O4 at equilibrium.

Be sure to round to the correct number of significant figures.

Based on your calculations, indicate whether each statement is True (T) or False (F):

1. Each experiment started with a different initial concentration of N₂O4

2. The ratio ([NO₂1/[N₂O4]) is equal to a constant value.

3. The ratio (2 [NO₂]/[N₂O4]) is equal to a constant value.

4. The ratio ([NO₂)/(N₂Oa]) is equal to a constant value.

5. Each experiment reached a different set of equilibrium concentrations.
