3 cards from this section. Quick, good the night before a test.
What is required for a reaction to occur according to collision theory?
Think about what happens before molecules can transform.
Define activation energy in your own words.
Consider it as a threshold or barrier that must be overcome.
What is collision theory primarily concerned with?
Think about the broader context of what happens after collisions.
True or False: Activation energy can be lowered by the presence of a catalyst.
Consider how catalysts affect reaction dynamics.
A chemical reaction follows the Arrhenius equation. If the rate constant at temperature 300K is observed to be 0.5 s⁻¹ and at 310K is 0.8 s⁻¹, determine the activation energy of the reaction.
Remember to convert the gas constant R into consistent units when performing calculations.
A researcher finds that the activation energy for a reaction is 75 kJ/mol. If the temperature is increased from 300K to 320K, predict how the reaction rate changes.
Think about the effect of a small temperature increase on collision energy and rates.
