Chapter 14 Flashcards
5 variables that effect reactions
Temperature, Pressure, Time, Catalyst, Concentration
5 types of reactions
Exothermic, Endothermic, Replacement, Neutralization, and Combustion
Used to slow down a reaction
Inhibitor
AMU
Atomic Mass Unit
A solvent that does not participate in the reaction - simply a carrier
Diluent
General categories of reactors
Continuous and Batch
5 types of reactors
Stirred, Fixed bed, Fluidized bed, Tubular, Furnace
5 factors to consider in reactors
Corrosion, Safety devices, Heating media, Cooling media, and Instrumentation
A collection of equipment designed together to produce a certain product
System
Doubles for every ____ degree Celsius increase in reactor
10
Increase in this increases gas reaction time. Occurs in liquids some of the time.
Pressure
Higher this make a faster reaction, but also expels or absorbs more heat
Concentration
Time in contact with catalyst
Contact Time
Time reactants in contact with catalyst in the reaction
Reaction Time
Time reactants in vessel overall
Residence Time
Two negatives with improper agitation
Development of hot spots
Reaction doesn’t happen right
Increases reaction rate
Catalyst
3 types of catalyst
Adsorption, Intermediate, Inhibitor
Catalyst that contacts surface of reactant
Adsorption catalyst
Catalyst that forms a product that is not complete. It is consumed before reaction complete, and another catalyst will be needed to complete the reaction
Intermediate catalyst
Catalyst that slows down reaction
Inhibitor
Catalyst that kills a reaction
Poison
Two chemicals you MUST have an inhibitor with
Vinyl Chloride Monomer and 1-3 Butadiene
Reaction that removes unwanted ions - usually in water treatment
Replacement
