Dinitrogen tetroxide, 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 the following statements are true, T, or false, F. At equilibrium, we can say that: 1. The concentration of NO2 is equal to the concentration of N2O4 2. The rate of dissociation of N2O4 is equal to the rate of formation of N2O4 3. The rate constant for the forward reaction is equal to the rate constant of the reverse reaction. 4. The concentration of NO2 divided by the concentration of N2O4 is equal to a constant. Enter T or F in the boxes below
