What else can I help you with?
Do catalysts decrease or increase energy required to begin a reaction?
Catalysts decrease activation energy.
What must be done to increase the rate of reaction?
Temperature
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.
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.

What must be done to increase the rate of reaction?
Temperature
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.

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).
Why does an increase reaction temperature generally increase the reaction rate?
All chemical reactions must be thought of as collisions between the particles of reactants and products. As the temperature of the reaction increases, the energy of the particles also increases and so there is a greater chance of more collisions occuring, and as a result, in general, an increase in reaction temperature increases the reaction rate
