1. If a reaction is first-order with respect to a particular reactant, when the concentration of that reactant
is increased by a factor of 2, the reaction rate will _.
A) increase by a factor of 2.
B) remain constant.
decrease by a factor of 2 .
Explain why a probability function is needed to determine whether a process will be spontaneous or not
A spontaneous reaction is one that does occur under a specific set of conditions, whereas a non-spontaneous
reaction is one that does not occur under a
Electrolytic Cell Form Define an electrolytic cell and explain all of the properties of such a cell
An electrolytic cell is a type of cell in which an external
energy sources drives an otherwise nonspontaneous reaction.
This non-spontaneous reaction can o

Covalent bonding involves atoms that share electrons. A polar
covalent bond, however, can be charged in the sense that it has
both a positive pole and a negative pole like a magnet. Explain
In your previous studies last semester, you encountered reactions went to
completion and were written A + B C + D. You are now learning about
reactions that achieve equilibrium and are written A + B C + D. Give the
definitions of both ty
Equilibrium Forum 2
Equilibrium is the principle that all natural processes involve a reverse reaction
(physical scientists call this principle microscopic reversibility). Explain why
the definition of equilibrium constants is a natural consequence of thi
Free Energy Forum
Mathematically define free energy and explain how it is used to determine if a
reaction is spontaneous or not or is at equilibrium
Gibbs Free Energy is another state function used to determine spontaneity of a
process. Gibbs Free energy
Henry's Law Forum
Describe the conditions under which Henry's Law is applicable.
Describe the mechanism by which equilibrium controls Henry's Law
Henry's law states, the solubility of a gas is directly
proportional to the partial pressure of the gas above
Galvanic cell forum
Define a galvanic cell and explain all of the properties of such a cell
An electrochemical cell is a system that consists of
electrodes that dip into an electrolyte and in which a
chemical reaction either uses or generates an electrica
Describe the meaning of the statement "colligative properties depend on the
number but not the nature of solute molecules". Describe what is meant
by the Van Hoff factor and relate it to the previous statement.
Solubility Equilibria Insoluble, or more correctly slightly soluble, salts can also be explained in
terms of equilibrium chemistry. A slightly soluble salt is in equilibrium with the small number of
ions that dissolve in solution. Consider a general salt,
CHAPTER 13 KINETICS
0480. If the rate law is Rate = k[NO]2[Cl2], the order with
respect to NO is 2 (second order), and the order with
respect to Cl2 is 1 (first-order). The overall order is 2 + 1 =
The second-order integrated
Why is Hesss Law Important in Thermochemistry?
Enthalpy change for a reaction can be found by using standard enthalpies of formation and taking the
sum of the products minus the sum of the reactants. Being that there are various compounds in the
