Dinitrogen tetra oxide is a colorless gas at room temperature. It can dissociate

Question

Dinitrogen tetra oxide is a colorless gas at room temperature. It can dissociate into nitrogen dioxide, which is a reddish brown gas. Three experiments were run starting with different initial amounts of N_2O_4(g) (N_2O_4]_0 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_2 and N_2O_4 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):

Explanation / Answer

1) True (statement is mentioned in the question itself)

2) Keq = [NO2]2/[N2O4]

Thus, the statement is false, as the above ratio is constant.

3) False

4) True

5) True as the initial concentration of the reactant are different in different reactions.
