Reaction rate trivia questions
Chemical reaction rate describes how quickly what happens?
Answer: Reactants are converted into products
Bonus fact: Reaction rate can be expressed as a change in concentration per unit time.
Which change usually increases the rate of many chemical reactions?
Answer: Raising the temperature
Bonus fact: Higher temperature gives particles more kinetic energy and increases the fraction of collisions able to overcome activation energy.
What does a catalyst do to increase reaction rate?
Answer: Provides a pathway with lower activation energy
Bonus fact: A catalyst speeds both forward and reverse reactions without being consumed overall and does not change the equilibrium position.
In chemistry, what does a rate law relate to a reaction's speed?
Answer: The concentrations of reactants
Bonus fact: Rate laws describe how changing reactant concentrations changes reaction rate.
