Batch and Stirred Flow Reactors (PSR)

• How is energy treated in Batch reactors when the reactor is not isothermal?
• Derive the temperature evolution equation for an adiabatic, constant pressure reactor.
• How does this change for an adiabatic, constant volume reactor?
• Derive the PSR species equation for mass fraction $y_i$ assuming equal mass flow rates in and out of the reactor.
• What is the physical meaning of $\tau = m/\dot{m}$?
• Does the temperature of a PSR increase, decrease, or stay the same with decreasing $\tau$?
• For $\tau\rightarrow\infty$ what is the corresponding reactor state?
• For $\tau\rightarrow 0$ what is the corresponding reactor state?
• If you model a campfire as a PSR, if you blow harder on the fire, are you increasing or decreasing $\tau$?
