Study Notes
- The study notes cover chemical kinetics, focusing on reaction rates, rate laws, activation energy, and reaction mechanisms.
Reaction Rate
- For a reaction $aA + bB \rightarrow cC + dD$, the rate can be expressed in terms of the change in concentration of reactants and products over time. $Rate = -\frac{1}{a}\frac{d[A]}{dt} = -\frac{1}{b}\frac{d[B]}{dt} = \frac{1}{c}\frac{d[C]}{dt} = \frac{1}{d}\frac{d[D]}{dt}$
Rate Law
- Expressed as $Rate = k[A]^x[B]^y$.
- $k$ represents the rate constant.
- $x$ signifies the order of the reaction with respect to reactant A.
- $y$ indicates the order of the reaction with respect to reactant B.
- The overall reaction order is the sum of x and y ($x + y$).
- Rate law must be determined through experimentation.
Zero Order Reactions
- Rate is constant and independent of reactant concentration: $Rate = k[A]^0 = k$.
- A plot of [A] vs t yields a straight line.
- Half-life ($t_{1/2}$) is calculated as $t_{1/2} = \frac{[A]_0}{2k}$.
First Order Reactions
- Rate is directly proportional to the concentration of one reactant: $Rate = k[A]^1 = k[A]$.
- A plot of $\ln[A]$ vs t is linear.
- Half-life ($t_{1/2}$) is constant: $t_{1/2} = \frac{0.693}{k}$.
Second Order Reactions
- Rate is proportional to the square of the concentration of one reactant: $Rate = k[A]^2$.
- Plotting $\frac{1}{[A]}$ vs t results in a linear relationship.
- Half-life ($t_{1/2}$) is inversely proportional to the initial concentration: $t_{1/2} = \frac{1}{k[A]_0}$.
Activation Energy
- Activation energy is the minimum energy needed for a reaction to occur.
Arrhenius Equation
- Describes the relationship between the rate constant, activation energy, and temperature: $k = Ae^{-E_a/RT}$.
- $A$ is the frequency factor.
- $E_a$ is the activation energy.
- R is the gas constant (8.314 J/mol·K).
- T is the temperature in Kelvin.
Two-Point Arrhenius Equation
- Used to find activation energy when rate constants at two temperatures are known: $\ln\frac{k_2}{k_1} = \frac{E_a}{R}(\frac{1}{T_1} - \frac{1}{T_2})$.
Catalyst
- A catalyst lowers the activation energy, thus speeding up the reaction.
Elementary Step/Reaction
- A reaction that happens in a single step
Reaction Mechanism
- Reaction Mechanism is the series of elementary steps that make up a reaction.
Rate Determining Step
- Rate Determining Step is the slowest step in a reaction mechanism.
