The following homogeneous gas-phase reaction takes places in a closed, constant volume 100 L batch reactor: A(g)-> 0.6 P(g) + 0.6 R(g), where rp= 0.3CA. The rate, rp, has units of mol L^-1 s^-1 and CA has units of mol L^-1. Pure compound A is in the reactor at an initial temperature and pressure, respectively, of 298 K and 0.97 atm. What is the total pressure that is achieved in the reactor when the conversion of A is 0.85? Express your answer in atmospheres, to one decimal place. For simplicity, you may assume that the gases behave ideally, where R is 0.0821 L atm /(mol K), the reactor is operated isothermally, and there is no pressure relief valve on the reactor.
