IB Chemistry - Kinetics (Chapter 13)

Reaction rates also depend on the…

concentration of the reactants.

Doubling the concentration of the reactant will…

double the rate.

Ratio remains constant as long as…

T constant.

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

rate constant and the concentration of the reactants.

Reaction order is always expressed in terms of…

reactant concentrations

The reaction order is not related to the…

stoichiometric coefficients of the balanced reaction.

Rate laws must be determined…

experimentally.

Rate laws are ________ dependent.

temperature

Catalysts are substances that are used to increase the…

rates of reactions.

Catalysts…

are not involved in the reaction.

Catalysts act by lowering the…

activation energy.

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

same phase.

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

elementary steps or reactions.

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.

The overall rate is determined by the….

slowest elementary step known as the rate determining step.
