(6 pts.) The following gas phase reaction system is conducted in an isothermal constant volume batch reactor. The reactor is charged with pure A with an initial concentration CAO AB ri = k CA B D r2 = K2 CB (3 pts.) Using the pseudo steady state approximation, derive an expression for the concentration of B in terms of CA. Do not solve for the exact form of CA(t). (3 pts.) Under what condition would this approximation fail? (6 pts.) The following gas phase reaction system is conducted in an isothermal constant volume batch reactor.
