Given the zero-order homogeneous gas-phase reaction A →2.7R, in a constant volume bomb starting with 80% A and 20% inert, we have Time 0 1 Total Pressure, atm 1 1.5 If we introduce A at a total pressure of 10 atm, no inerts, inerts, what will be the total pressure at t=1? If we introduce A at a partial pressure of 1 atm and inerts at 9 atm, what will be the total pressure at t=1? B takes place in the gas phase in a constant temperature reactor. Reactant A and diluent gas are 4. The irreversible reaction 2A fed in equimolar ratio, and the conversion of A is 85 percent.
