A flask is charged with 0.983 atm of N2O4 (g) as well as 0.752 atm NO2 (g) at 25 degrees C. Explain the equilibrium reaction is N2O4 (g) arrow pointing in both directions 2NO2 (g). After equilibrium is reached, the partial pressure of NO2 is 0.413 atm.a. Explain what is the equilibrium partial pressure of N2O4?
The partial pressure and Henry's law constants for SO2 and H2O2 are 2.7 ppm (KH = 1.2 mol L-1atm-1) and 4.9 ppb (KH = 1.0E5 mol L-1atm-1), respectively. Calculate the reaction rate of this process.
