Use molar flow rates and concentrations; DO NOT use conversion!

1. Parallel Reactions

2. Series Reactions

3. Complex Reactions: Series and Parallel aspects combined

4. Independent Reactions

Independent reactions typically occur in the catalytic cracking of crude oil to form gasoline.

What type of reaction is taking place?

There are two types of selectivity and yield: Instantaneous and Overall.

Example:                   desired product , rD=k1CA2CB
                    undesired product , rU=k2CACB
                        To maximize the selectivity of D with respect to U run at high concentration of A and use PFR
