How do changes in energy and temperature influence chemical changes?
The reaction rate is dependent on temperature (increasing the temperature the reaction rate increase) and activation energy.
Why is it necessary to specify the temperature when giving a value for k?
The rate constant, k, varies with temperature, so the temperature at which it has been determined must be given. In general a 10 oC temperature increase will double the rate of a chemical reaction.
What effect temperature have on reaction rate?
An increase in temperature speeds up the reaction rate.
Are the reaction-rate changes recorded in Table 11.4 consistent with the rule of thumb concerning the effect of a 10oC temperature increase on the rate of reactions?
no
What would happen to the rate of a reaction with rate law rate?
The rate of a reaction as described by a rate law is dependent on the concentrations of the reactants and their respective rate constants. If the concentration of a reactant increases, the rate of the reaction will typically increase proportionally, assuming other conditions remain constant. Conversely, if the concentration decreases, the rate of reaction will decrease. Additionally, changes in temperature or the presence of a catalyst can also significantly affect the reaction rate.
How do changes in energy and temperature influence chemical changes?
The reaction rate is dependent on temperature (increasing the temperature the reaction rate increase) and activation energy.
How do changed in temperature and activation energy compare in how they affect reaction rate?
Changes in temperature and activation energy have opposite effects on reaction rate.
How do changes in temperature and activation energy compare in how they affect reaction rate Apex?

How do changes in temperature and energy influence chemical changes?
Changes in temperature can speed up or slow down chemical reactions by affecting the kinetic energy of molecules. Higher temperatures generally increase the rate of reactions by providing more energy for molecules to collide and react. However, extreme temperatures can also denature proteins and disrupt the equilibrium of a reaction.
What does temperature have on reaction rate?
An increase in temperature speeds up the reaction rate.
Is the rate constant dependent on temperature?
Yes, the rate constant of a reaction is typically dependent on temperature. As temperature increases, the rate constant usually increases as well. This relationship is described by the Arrhenius equation, which shows how the rate constant changes with temperature.
What effect temperature have on reaction rate?
An increase in temperature speeds up the reaction rate.
What is the significance of the Arrhenius equation in da-chemistry?
The Arrhenius equation is important in chemistry because it helps us understand how the rate of a chemical reaction changes with temperature. It shows the relationship between the rate constant of a reaction and the temperature at which the reaction occurs. This equation is used to predict how changing the temperature will affect the rate of a reaction, which is crucial for many chemical processes and industries.
What changes the rate of a reaction?
* Presence of enzyme * Change in pH * Change in temperature * Change in salt concentration.
Is temperature essential in determining the reaction rate?
yes, as the reaction rate increases with increase in the temperature
Are the reaction-rate changes recorded in Table 11.4 consistent with the rule of thumb concerning the effect of a 10oC temperature increase on the rate of reactions?
no
