How many g of water are required to be mixed with 11.75 g of HgCl in order to make a 0.01 m solution? (Refer to the periodic table for atomic weights.) a.) 40 g
b.) 5,000 g
c.) 2 x 10^8 g
d.) 2 x 10^6 g

The general name for a substance added to a reaction that affects the rate but is not consumed in the reaction is called a.

a.)constituent
b.)catalyst
c.)complex
d.)reactant

The action of a catalyst can be explained in the following manner:

a.) The catalyst makes it possible for the reaction to take place by another path that makes possible reaction at a lower energy.
b.) The catalyst takes no part in the reaction but serves as a buffer between reactants and products.
c.) The catalyst prevents the reverse reaction.

d.) The catalyst lowers the temperature of the reactants.

The energy level necessary to enable a reaction to occur is called the energy.

a.) potential
b.) kinetic
c.) activation
d.) nuclear

Raising the temperature of a reacting system increases the rate of the reaction, but does NOT increase the:

a.) number of collisions
b.) average velocity of the reacting particles
c.) activation energy
d.) vibrational motions within the molecules
e.) fraction of the reacting particles which possess energies greater than the activation energy
