For a gas phase isothermal reaction 2AR+2S is 2 nd order according to A. A pure gas stream A at 1atm is fed into a batch reactor with constant volume, the system pressure increases by 30% in 3 minutes. a) Determine the conversion at 3 min. ( 2.5 mark) b) In the case of a constant pressure reactor, find the time it takes to achieve the same conversion as the above input flow. (2.0 mark) c) Input at a pressure of 1atm where 50% inert gas and 50% gas A. In the case of a constant pressure reactor, find the time it takes to achieve the same conversion as in question a.
