Lecture 2

Question 1

What is Stoichiometry?

Answer 1

-Show the relative proportion of reactant and products

Question 2

What are reaction kinetics?

Answer 2

-Time dependent reactions

Question 3

What are reactant and products?

Answer 3

-Reactants are on the left hand side and products are on the right hand side of a stotichiomertic equation

Question 4

What is a first order reaction?

Answer 4

A –> B
dC/dt = kc
ln(C(t)/C0) = -kt

Question 5

What is a second order reaction?

Answer 5

A + B –> B
dC/dt = kC^2
1/C(t) - 1/C0 = -kt

Question 6

What is a pseudo first order?

Answer 6

-When the concentration is held constant
-occurs in 2nd order reaction
dc/dt = -kCX

Question 7

What is reaction order?

Answer 7

-Rate at which the reaction occurs is determined by measuring concentration of react/prod.

Question 8

What is a steady state reaction?

Answer 8

-The rate of accumulation is equal to 0.
–> dc/dt=k
C-C0 = -kt

Question 9

What is a batch reactor?

Answer 9

-no inflow or outflow
-flow only enter once
-Equation: 1st order
dC/dt = -KC

Question 10

How are the reaction rate coefficients determined?

Answer 10

aA + bB –> cC + dD
n the coefficient is equal to:
–> n = a+b
dC/dt = kC^n

Question 11

What does the word cometabolism refer to?

Answer 11

-Constant pseudo 1st order
