Dinitrogen tetroxide, N2O4, is a colorless gas, which dissociates to give nitrogen dioxide, NO2, a reddish-brown gas. N204(g) 2NO2(g) a) 0.0300 mol N204 are placed in a 1.00-L flask at 25.0°C. After equilibrium is established, 0.0375 mol NO2 are present in the flask. Calculate the value of Kat 25.0°C. b) After equilibrium was attained in part a), the volume of the flask is changed so that the equilibrium pressure of N2O4 is doubled. What is the new volume of the flask?

Question
Dinitrogen tetroxide, N2O4, is a colorless gas, which dissociates to give nitrogen dioxide, NO2, a reddish-brown gas. N₂O(g) = 2NO2(g) a) 0.0300 mol N2O4 are placed in a 1.00-L flask at 25.0°C. After equilibrium is established, 0.0375 mol NO₂ are present in the flask. Calculate the value of K at 25.0°C. b) After equilibrium was attained in part a), the volume of the flask is changed so that the equilibrium pressure of N2O4 is doubled. What is the new volume of the flask?
