2 cards from this section. Quick, good the night before a test.
What does temperature measure in a chemical reaction?
Think about what happens to molecules when temperature increases.
How does increased temperature affect molecular collisions?
Consider how temperature relates to speed.
What is the effect of increasing temperature on reaction rates?
Recall the empirical observation regarding temperature changes.
Is it true that temperature affects the activation energy of a reaction?
Think about what activation energy signifies.
Calculate the new rate constant for a reaction with an activation energy of 75 kJ/mol when the temperature is increased from 298 K to 308 K using the Arrhenius equation.
Don't forget to convert energy from kJ to J when using the constants.
Design a hypothetical experiment where you investigate the effect of temperature on the rate of a specific reaction, detailing methodology and expected results.
Consider the types of measurements you'd need to reliably assess the rate.
