Integrated Rate Laws (17.4) Flashcards
- Explain the form and function of an integrated rate law. - Perform integrated rate law calculations for zero-. first-, and second-order reactions. - Define half-life and carry out related calculations. - Identify the order of a reaction from concentration/time data.
1
Q
What is the difference between rate laws and integrated rate laws?
A
- Rate laws describe how the concentrations of reactants change over time, providing equations that relate concentration to time.
- Integrated rate laws describe how the concentrations of reactants change over time, providing equations that related concentration to time.
2
Q
What is integrated rate laws?
A
Equations that show how reactant concentrations change over time.
3
Q
First-Order Integrated Rate Law
A
ln [A]= − kt + ln [A(initial)]
- Describes a reaction where the rate depends on the concentration of one reactant to the first power.
4
Q
Second-Order Integrated Rate Law
A
Describes a reaction where the rate depends on the concentration of one reactant to the second power or two reactants to the first power.
5
Q
Zero-Order Integrated Rate Law
A
Describes a reaction where the rate is constant and independent of the concentration of the reactant.
6
Q
Half-Life
A
The time it takes for half of a reactant to be consumed in the reaction.
