Mass & Energy Balances
This law states that mass cannot be created or destroyed in a chemical process.
What is the law of conservation of mass?
This is the process that describes the movement of mass from areas of high concentration to low concentration.
What is diffusion?
This reactor operates at steady state with continuous inflow and outflow.
What is a continuous stirred tank reactor/CSTR?
AIChE stands for this.
What is the American Institute of Chemical Engineers?
The first law of thermodynamics is also known as this.
What is the law of conservation of energy?
In an open system, this term represents the mass crossing system boundaries.
What is the mass flow rate?
This equation is used to relate vapor pressure and temperature.
What is Antoine's Equation?
This reaction uses reactants and catalysts that are in different phases.
What is a heterogeneous reaction?
AIChE was founded in this year.
What is 1908?
The second law of thermodynamics states that this property always increases in a closed system.
What is entropy?
The unit of energy commonly used in chemical engineering, symbolized as "J."
What is a Joule?
This dimensionless group is used to determine if fluid flow is laminar or turbulent.
What is the Reynold's Number?
This bioreactor continuously exchanges culture media and cells while letting product and waste exit through a membrane.
What is a perfusion reactor?
The Haber-Bosch process developed by Fritz Haber produces this.
What is ammonia?
A process that occurs at a constant pressure is called this.
What is an isobaric process?
This is the amount of energy needed to raise the temperature of 1 gram of water by 1°C.
What is a calorie?
This set of equations is used to describe fluid flow.
What are the Navier-Stokes equations?
The Arrhenius equation explains how this factor affects reaction rate.
What is temperature?
The first AIChE conference was held in this city.
What is Pittsburgh, PA?
The Gibbs free energy equation is ΔG = ΔH - TΔS. If ΔG is negative, the reaction is classified as this.
What is spontaneous?
This term describes the amount of energy required to change one mole of a substance from liquid to vapor.
What is latent heat of vaporization?
This type of reaction occurs at a rate that is directly proportional to the concentration of one reactant.
What is a first-order reaction?
A CSTR is typically assumed to be this.
What is well-mixed?
This chemical engineer developed the concept of unit operations.
Who is Arthur D. Little?
This property, often called the "effective pressure" of a real gas, accounts for deviations from ideal gas behavior.
What is fugacity?
