QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Factors Affecting Reaction Rate.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.

A reaction between two gases is carried out at high pressure. What effect does increasing the pressure have on the reaction rate?
A reaction between two solutions is found to be faster at higher concentrations. What does this suggest about the effect of concentration on reaction rate?
A reaction is carried out at 25°C and then at 35°C. What is the expected effect on the reaction rate?
A reaction is carried out in a closed container. If the pressure is doubled, what happens to the rate of a reaction between two gases?

Increasing the concentration of reactants generally ________ the rate of reaction.
The addition of a catalyst to a reaction mixture will ________ the activation energy required for the reaction.
The minimum energy required for a reaction to occur is called ________.
The rate of a chemical reaction depends on the frequency of ________ between reactant particles.
True or False: A catalyst increases the rate of a reaction by being consumed in the reaction.
True or False: All reactions speed up when the pressure is increased.
True or False: Catalysts are specific to certain reactions and may not work for all reactions.
True or False: Catalysts lower the activation energy of a reaction.
