![Dinitrogen tetraoxide is a colorless gas at room temperature. It can dissociate into nitrogen dioxide, which is a reddish brown gas.
N204(g) =2 NO2(g)
Three experiments were run starting with different initial amounts of N,0,(g) ([N,O,]o 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 NO2 and N204 at equilibrium.
Be sure to round to the correct number of significant figures.
