Question

please show ALL work.

Dinitrogen tetraoxide 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. Based on your calculations, indicate whether each statement is True (T) or False (F): Each experiment started with a different initial concentration of N_2O_4. The ratio ([NO_2]/[N_2O_4]) is equal to a constant value. The ratio (2 [NO_2]/[N_2O_4]) is equal to a constant value. The ratio ([NO_2]_2/[N_2O_4]) is equal to a constant value. Each experiment reached a different set of equilibrium concentrations.

all the three experiment have different initial concentration( 3.5,3.0 & 2.6)

The ratio value of [NO2]/ [N2O4] in all three experiment have different value

1.4 , 1.5 & 1.7 is not a constant value.

      3. Answer is FALSE

The ratio value of 2[NO2]/ [N2O4] in all three experiment have different value

2.7, 3.0 & 3.3 is not a constant value.

4.Answer is TRUE

The ratio value of [NO2]2/ [N2O4] in all three experiment have same value3.9, 3.9 & 3.9 is a constant value.

     5. Answer is TRUE

Each having different set of Equilibrium concentration
