The pressure dependence at a constant temperature of the dynamic viscosity of a reacting mixture N2O42NO2 given was calculated at 300-1000K and 1-300 bars by using a pseudocritical constant method and from semiempirical mixing rules for the Lennard-Jones potential force. Both methods gave almost identical results, which differ by approximately 5-8 percent from experimental values. Author
