What are the differences between differential and integrated rate laws?
Differential rate law: Shows how rate changes with concentration. | Integrated rate law: Shows how concentration changes with time.
What are the differences between intermediates and catalysts?
Intermediates: Species formed and consumed during the reaction, but not in the overall equation. | Catalysts: Substances that speed up a reaction without being consumed.
What is the effect of increasing temperature on the rate constant (k)?
Increasing temperature generally increases the rate constant (k), leading to a faster reaction.
What is the effect of a catalyst on the activation energy of a reaction?
A catalyst lowers the activation energy of a reaction.
What is the effect of doubling the concentration of a reactant in a first-order reaction?
The reaction rate doubles.
What is the effect of doubling the concentration of a reactant in a second-order reaction?
The reaction rate quadruples.
What are the general steps to determine rate laws experimentally?
- Run multiple trials with different reactant concentrations. 2. Observe how the rate changes with each concentration change. 3. Use this data to determine the reaction orders and rate constant.
