Assume that decomposition of HNO3 can be represented by the following equation
4HNO3(g)⇌4NO2(g)+2H2O(g)+O2(g)
and the reaction approaches equilibrium at 400 K temperature and 30 atm pressure. At equilibrium partial pressure of HNO3 is 2 atm.
Calculate Kc in (mol/L)3 at 400 K :(Use : R=0.08 atm−L/mol−K)
