If the temperature of a chemical reaction is increased the reaction rate?

It depends if the reaction is endothermic (requires heat/energy) or is exothermic (requires no heat/energy and produces heat/energy). In general, most reactions are endothermic and require some amount of energy to 'go' and hence, an increase in temperature will increase the rate of reaction. However, in exothermic reactions, introducing heat can halt the reaction as well as reverse it, if said reaction is reversible.

As temperature decreases the rate of an enzyme-catalyzed reaction also decreases why?
Just like many other chemical reactions, the rate of an enzyme-catalyzed reaction will decrease with temperature because of the decrease in the number of high energy collisions between particles.
What are the 5 important factors that influence the rate of a chemical reaction?
Temperature Surface area/phase of reactants Concentration of reactants Presence of catalyst Activation energy of reaction
What effects the rate constant of a reaction?
The temperature of the system
Why does surface area of a reactant influence the rate of the of the reaction?
by pooing on the leg
Undergo no chemical change during a chemical reaction?
A catalyst doesn't undergo a chemical change during a chemical reaction.
What do concentration surface area and temperature have in common?
They can all affect the rate of a chemical reaction.
An increase in temperature will cause the rate of a chemical reaction to?
Increasing the temperature the dissolving rate increase.
As the temperature of a chemical reaction in the gas phase is increased the rate of the reaction increases because?
Increasing the temperature generally increases the speed with which molecules move.
Is the rate of a chemical reaction dependent of temperature?
In general, as temperature rises, so does reaction rate. This is because the rate of reaction is dependent on the collision of the reacting molecules or atoms. As temperature rises, molecules or atoms respond with increased motion, increasing the collision rate, thus increasing the reaction rate.
What happens to the temperature when the mass is increased in a chemical reaction involving magnesium and hydrochloric acid?
The temperature will increase the higher the mass of magnesium you add. It will increase the rate of the reaction.
How do you enhance rate of reaction in CSTR?
rate of a reaction can be increased by increasing the temperature if the reactor
How might the chewing of food be related to the rate of chemical reaction digestion that occurs in your body?
Chemical reaction rate is increased by: -increased surface area -increased temperature -increased concentration of reactants -presence of a catalyst Chewing food essentially breaks up large chunks of food into smaller bits, increased total surface area for digestion.
How are temperature and the Arrhenius theory related?
The reaction rate of a chemical reaction is dependent on temperature.
What leads to an increase in the rate of a chemical reaction?
Either (or both) an increase in the reactants or temperature will increase the rate of a chemical reaction.
Which of the following tends to increase the rate of a chemical reaction?
Increasing the temperature of the reactants can increase the rate of the chemical reaction.
Does temperature effect the rate of chemical reaction?
yes.
How do changes in temperature and energy influence chemical changes?
The reaction rate is dependent on temperature (increasing the temperature the reaction rate increase) and activation energy.
