Rxns and accumulation only for steady steady-MAT BALANCES:-draw pics and write down all info always!!!-Examples:-Find V in 1 st order reaction (A to B) given concentrations of A in and out, flow rate of A(same for in and out), and given rate constant conc in (flowrate)=conc out (flowrate) + rateconstant(conc out )(volume) -...
