What you mean by FSP

One defintion is Foreign Service Pension.

Which of the following is a strong acid

HCI (Hydrochloric acid)

Why does a numerically large Keq mean that the products are favored in an equilibrium system

Because it means that the equilibrium mixture contains more product than reactants.

What are the forces holding each type of crystalline solid together

Electro-magnetic.

An increase in temperature will cause the rate of a chemical reaction to

increased temperture causes rate or reaction to increase.

What is the equation for reaction rate

For a reaction whose slowest step is

mX + nY ----> aXY

rate = k * [X]m * [Y]n

where k is the rate constant; brackets represent concentrations; m and n are exponents on the concentrations of X and Y, respectively

Zinn's main purpose for writing A People's History of the United States was to give an accurate and detailed account of American history from the victim's point of view.

Which solid exhibits more than one kind of chemical bonding

diamond

What happens to the reaction rate as the reactants get used up in a reaction

The rate of the reaction begins to decrease as reactants are used up

Which equation is an expression of the rate law

Rate = k[A]m[B]n

What does a high melting point temperature indicate about a substance

Strong Intermolecular Forces attract the molecules

What does it mean if keq1

I suspect it could be " k eq 1" , or "k =1".

What characterizes a crystalline solid when it breaks

The break follows the crystal structure.

Which of the following Ka values represent the weakest acid

Ka= 1.62 x 10-12

What is Ka for HCN aq H aq CN aq

Ka = [H+][CN-]

---------------

[HCN]

What increases the chance of reaction when two molecules collide

increasing the concentration in the molecue

What most likely accounts for the difference between curve A and curve B on the energy diagram

The reaction described by curve B is occurring with a catalyst.
