Chemical Kinetics and Equilibrium

Question 1

How to determine overall order of a rxn?

Answer 1

Sum the exponents in the rate calculation

Question 2

What’s the rule of thumb for relationship b/w reaction rate and T?

Answer 2

Rate x 2 for +10ºC

Question 3

Explain the two types of catalysts

Answer 3

Homogenous: catalyst in same phase as reactants
Heterogeneous: catalyst in different phase from reactants

Question 4

When can you use stoichiometric coefficients as the orders of reaction?

Answer 4

1. When the reaction occurs in a single step and the balanced overall rxn reflects entire process
2. When complete rxn mechanism is given and rate-determining step is given.
