ili. Rxn 3, catalytie reaction using concentrations

i Rxn 1, using concentrations

\text { Rxn 1: } \mathrm{C}_{2} \mathrm{H}_{2}+2 \mathrm{Cl}_{2} \rightarrow \mathrm{C}_{2} \mathrm{H}_{2} \mathrm{Cl}_{4}

c. Write the rate law for each reaction and indicate the proper units (using s (for time),mol/l (for conc.), atm (for partial pressure), and g for cat. wt.) for each rate constant,as well as for the equilibrium constant for reversible reactions.

b. Show the Stoichiometric Table for each reaction.

i Rxn 1, feed is 50% C2H/50% Cl2

For each case, if the feed is stoichiometric, say so, if not, identify the Limiting Reactant

Use these three elementary reactions:

iii. Rxn 3: feed is 35% CH/60% F/5% H2

\mathrm{Rxn} 3: 2 \mathrm{~F}_{2}+\mathrm{CH}_{4} \rightarrow 2 \mathrm{H}_{2}+\mathrm{CF}_{4}

\operatorname{Rxn} 2: 3 \mathrm{H}_{2}+\mathrm{N}_{2} \rightleftharpoons 2 \mathrm{NH}_{3}

ii. Rxn 2, feed is 25% N/75% H2

d. Now assume the value of the rate constant in terms of the Limiting Reactant is 1.4 (withthe appropriate units) and calculate the rate constant for each of the other species(including the products) in each reaction.

a. Determine the limiting reactant (LR) and show the stoichiometric table.

b. Calculate the equilibrium conversion.

What conversion will be obtained in a V= 758 e PFR?

e. If the reaction is run instead in a series of two CSTR's, each with a volume of XV,what will the conversion be at the outlet of each CSTR?

a. Find the CSTR volume to get 60% conversion.

b. Repeat for a single PFR.400

c. Repeat parts (a) and (b)but for 80% conversion.

250d. For what conversion(between 60% and 80%)will the single CSTR volume be the same as20015010050that for the single PFR?What's the volume?
