CHEMICAL REACTION: A chemical reaction is a process that leads to the transformation of one set of Chemical substances to another.
How can we count them? Reaction
Batch Reactor Batch Continuous Stirred Tank Reactor (BCSTR)
Flow Reactor CSTR
Flow Reactor Continuous Stirred Tank Reactor (CSTR) Tubular Reactor
Tubular Reactor Plug Flow Reactor (PFR) Packed Bed Reactor (PBR)
Tubular Reactor Fluidized bed Reactor (FBR) Bubble Column Reactor (PBR)
Industrial Reactors
The Rate of Reaction Chemical kinetics is the study of rates of chemical reactions
The Rate of Reaction What factors influence the rate of a reaction? Once we specify a particular reacting system, the factors that influence the rate of a reaction are (1) temperature, (2) concentrations of reactants, (3) physical state of reactants, (4) presence of a catalyst. The rate equation (Rate Law) is an algebraic equation of a Chemical Reaction that links the Reaction Rate with concentrations or pressures of reactants and constant parameters (normally rate coefficients and partial Reaction Orders) Independent of the type of reactor (Batch or Continuous)
The Rate of Reaction Rate of Disappearance : Rate of Formation (Generation): Reaction in presence of Catalyst number of moles of A reacting per unit time per unit mass of catalyst (mol/s. g catalyst)
The Rate of Reaction
