14.1 Rates and Rate Expressions

A zero order reaction does not depend on the concentration of a reactant.

This value is the order with respect only to B.

This value is the order with respect only to A.

Correct, the overall order is the sum of the order with respect to A and with respect to B.

The order with respect to both A and B must be considered.

 The overall order is simply the sum of the exponents in the rate law. 

What is the overall order of the reaction expressed with the rate law, rate = k[A]2[B]?

Intro to Chemical Kinetics Example 1

Consider the following graph of the concentration of a
substance X over time. Is each of the following statements
true or false? (d) As time progresses,
the curve will eventually turn downward toward
the x-axis. [Section 14.2]

Kinetics Of Life: About my research

An automotive fuel injector dispenses a fine spray of
gasoline into the automobile cylinder, as shown in the
bottom drawing here. When an injector gets clogged, as
shown in the top drawing, the spray is not as fine or even
and the performance of the car declines. How is this observation
related to chemical kinetics? [Section 14.1]

Suppose that for the reaction K + L → M, you monitor
the production of M over time, and then plot the following
graph from your data:

(b) Is the reaction completed at t = 15
min? [Section 14.2]

[BOOK CHEM] Clutch Version

Chemical Kinetics is the study of factors affecting reaction rates, which examines the speed by which reactants are consumed to make products.

Average Rate of Reaction

Average (General) Rate is the change in the concentration of a compound over a period of time.

Arrhenius Equation

The Arrhenius Equation&nbsp;illustrates the temperature dependence of the rate constant k.&nbsp;

Rate Law

Rate Law represents an equation for a chemical reaction that connects the reaction rate with the concentrations or pressures of the reactants and the rate constant.&nbsp;

Factors Influencing Rates

There are 4 major factors that directly influence how fast or slow a reaction proceeds.

Stoichiometric Rate Calculations

When the rate of one compound is know, the rate of another compound is calculated through rate-to-rate comparison.

Collision Theory

According to Collision Theory:chemical reaction is successful when 2 energetic reactants successfully collide.

Integrated Rate Law

When we include the variable of time to our Rate Law then we obtain the Integrated Rate Laws.&nbsp;

Catalyst

Catalyst is a substance that increases the rate of reaction by lowering the Activation Energy (Ea) of a reaction.

Instantaneous Rate

<div title="Page 1">&nbsp;Instantaneous Rate is the rate a reaction at any particular point in time.</div>

Reaction Mechanism

<div title="Page 1">A Reaction Mechanism is a step-by-step sequence of elementary steps by which an overall chemical change occurs.</div>

Half-Life

Half-Life is the time it takes for half&nbsp;of a reactant to decay in a certain time period.

Energy Diagrams

Energy Diagram represents a curved plot illustrating the energies of reactants, products and transition states of a reaction.
