The rate constant decreases.
What else can I help you with?
What happens to the rate constant as activation energy increase?
The rate constant decreases.
If an object moves with constant acceleration what happens to the velocity?
The velocity increases at a constant rate.
What happens when you add a catalyst to the rate constant k?
Adding a catalyst typically increases the rate constant k by providing an alternative reaction pathway with lower activation energy. This allows the reactants to more easily convert to products, resulting in a faster reaction rate.
Will affect the rate of the constant according to the Arrhenius equation changing which factors?
The rate constant in the Arrhenius equation is impacted by temperature and activation energy. Increasing temperature generally increases the rate constant as molecules have more energy to overcome activation barriers. Similarly, lowering the activation energy required can lead to a higher rate constant.
When mass and volume change what happens to the density?
When mass increases and volume stays constant, the density increases. When volume increases and mass stays constant the density decreases. When they both change, then the density will depend on the rate of change of mass and the rate of change of volume.
What happens to the rate constant of a chemical reaction when the temperature increases?
Increasing the temperature will cause there to be an increase in kinetic energy. This results in an increase in collision frequency, and eventually an increase in rate of reaction as well.
Does the rate constant vary with temperature?
Yes, the rate constant of a reaction typically increases with temperature due to the higher energy of the molecules, leading to more frequent and energetic collisions.
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.
How does temperature impact the rate constant in chemical reactions?
Temperature has a direct impact on the rate constant in chemical reactions. Generally, as temperature increases, the rate constant also increases. This is because higher temperatures provide more energy to the reacting molecules, allowing them to collide more frequently and with greater force, leading to a faster reaction rate.
Why rate constant decrease when activation increase in arrhenius equation?
The rate constant in the Arrhenius equation decreases as the activation energy increases because a higher activation energy means that fewer molecules possess the required energy to overcome the energy barrier and react. This results in a lower frequency of successful collisions between reacting molecules, leading to a decrease in the rate constant.
How does the rate constant change with temperature in a chemical reaction?
The rate constant of a chemical reaction generally increases with temperature. This is because higher temperatures provide more energy for molecules to react, leading to a faster reaction rate.
What is the relationship between the rate constant and temperature in a chemical reaction?
The rate constant of a chemical reaction generally increases with temperature. This is because higher temperatures provide more energy for molecules to react, leading to a faster reaction rate.
