What must be done to increase the rate of reaction?
Temperature
Do catalysts decrease or increase energy required to begin a reaction?
Catalysts decrease activation energy.
What is a type of reaction that produces an decrease in temperature?
An endothermic reaction is a type of chemical reaction that absorbs heat from its surroundings, leading to a decrease in temperature. During this process, the energy required for the reaction to occur is taken in from the environment, resulting in a cooling effect. Examples of endothermic reactions include photosynthesis and the dissolution of certain salts in water.
What are the 2 reasons why a decrease in temperature slows a chemical reaction?
Decreasing the temperature reduces the kinetic energy of the molecules involved. This means that fewer molecules have the activation energy required to actually react. It also means that molecules will collide less often.
What is indotermic reaction?
Indothermic reaction is a chemical reaction that absorbs heat from its surroundings, causing a decrease in temperature. Energy is required for the reaction to occur, making it endothermic. Examples include the reaction between baking soda and vinegar.

Do catalysts decrease or increase energy required to begin a reaction?
Catalysts decrease activation energy.
How does an endothermic reaction result in a decrease in temperature?
An endothermic reaction absorbs heat from its surroundings, causing a decrease in temperature. This is because the energy required for the reaction to occur is taken from the surrounding environment, leading to a cooling effect.
What effects does temperature have on reaction rate?
An increase in temperature speeds up the reaction rate.
An increase in temperature will cause the rate of a chemical reaction to?
Increasing the temperature the dissolving rate increase.

What would decreses the rate of reactant?
Decreasing temperature, decreasing concentration of reactants, increasing the activation energy required for the reaction, and introducing an inhibitor can all decrease the rate of a reaction.
Definition of endothermic?
Endothermic reactions or processes absorb heat from their surroundings to proceed, causing a decrease in temperature of the surroundings. Energy is required for the reaction to occur, resulting in a decrease of the system's internal energy.
How do changes in temperature and activation energy compare in how they affect reaction rate Apex?
Changes in temperature and activation energy have opposite effects on reaction rate.
Which of these would be expected to increase the rate of sa chemical reaction?
Increasing temperature, increasing concentration of reactants, and adding a catalyst are all factors that can increase the rate of a chemical reaction. This is because they either provide more energy for the reaction to occur (temperature), increase the frequency of reactant collisions (concentration), or lower the activation energy required for the reaction to proceed (catalyst).
