1

Reaction rates also depend on the…

concentration of the reactants.

New cards
2

Doubling the concentration of the reactant will…

double the rate.

New cards
3

Ratio remains constant as long as…

T constant.

New cards
4

Rate Laws express the relationship between the rate of the reaction to the…

rate constant and the concentration of the reactants.

New cards
5

Reaction order is always expressed in terms of…

reactant concentrations

New cards
6

The reaction order is not related to the…

stoichiometric coefficients of the balanced reaction.

New cards
7

Rate laws must be determined…

experimentally.

New cards
8

Rate laws are ________ dependent.

temperature

New cards
9

Catalysts are substances that are used to increase the…

rates of reactions.

New cards
10

Catalysts…

are not involved in the reaction.

New cards
11

Catalysts act by lowering the…

activation energy.

New cards
12

Homogeneous catalysis refers to the situation where the reactants and catalyst are in the…

same phase.

New cards
13

Many reactions occur by multi-step processes-meaning they involve two or more…

elementary steps or reactions.

New cards
14

Intermediates may be produced that are later consumed in the reaction. The net result is that they…

do not show up in the overall net reaction.

New cards
