Chemical Reaction Engineering - Conversion and Reactor Sizing

Name one type of reactor.

Define the conversion of species A?

• The rate of reaction

• The total volume of the reactor

• The number of moles of A reacted per mole of A fed

• The number of moles of A fed

In a batch reactor, what is the equation for the number of moles of A that remain after time t?

• N_A = N_A0 / X

• N_A = N_A0 + X

• N_A = N_A0 - X

• N_A = N_A0 * X

What is the maximum value of conversion X for irreversible reactions?

• X = 0

• X = 1.0

• X = 0.5

• X = 0.8

What is the design equation for a CSTR?

• V = -r_A / F_A0

• V = F_A0 / -r_A

• V = F_A0 * X / -r_A

• V = X / F_A0

What does the term 'space time' refer to?

• The time necessary to process one reactor volume of fluid

• The total volume of the reactor

• The rate of reaction

• The concentration of reactants

Which equation is used to express the rate constant k?

• Mole Balance Equation

• Ideal Gas Law

• Levenspiel Equation

• Arrhenius Equation

What is the relationship between conversion and reactor volume?

• Inversely proportional

• Directly proportional

• No relationship

• Exponential relationship

What is the primary factor affecting the rate constant in gas-phase reactions?

• Volume

• Concentration

• Pressure

• Temperature

In a PFR, what is the design equation?

• V = F_A0 * X / -r_A

• V = X / F_A0

• dV/dX = F_A0 / -r_A

• V = -r_A * dX
