What else can I help you with?
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.
On what does the rate constant depend?
The rate constant depends on factors such as temperature, concentration of reactants, and presence of a catalyst.
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.
How does temperature affect the rate constant in a chemical reaction?
Temperature affects the rate constant in a chemical reaction by increasing it. As temperature rises, molecules move faster and collide more frequently, leading to a higher likelihood of successful reactions. This relationship is described by the Arrhenius equation, which shows that the rate constant is exponentially dependent on temperature.
According to the Arrhenius equation changing which factors will affect the rate constant?
The factors that can affect the rate constant in the Arrhenius equation are temperature and activation energy. Increasing the temperature will increase the rate constant, as reactions occur more rapidly at higher temperatures. Similarly, changing the activation energy required for the reaction will also impact the rate constant.
How do you differentiate between reaction rate and specific rate constant?
The reaction rate is the rate at which the moles of substance change that varies with both temperature and concentration of the reactants. The specific rate constant is a proportionality constant that will vary only with temperature.
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.
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.
On what does the rate constant depend?
The rate constant depends on factors such as temperature, concentration of reactants, and presence of a catalyst.
Specific rate constant?
specific rate constant is an experimentally determined proportionality constant which is different for different reactions and changes only with temperature.
Define a specific rate constant?
The specific rate constant a proportionally determined constant that is usually different for various reactions with changes in temperature.
Does the gas constant R vary with temperature?
No, the gas constant, or any constant, is constant meaning it doesn't change.
Is the temperature constant or does it vary throughout the fridge?

What is the constant in a experiment on melting rate of ice?

Will affect the rate of the constant according to the Arrhenius equation changing which factors?

Similarly, lowering the activation energy required can lead to a higher rate constant.
Does tea cool at a constant rate?
Yes, assuming that the environment in which the tea is "living" stays a constant temperature. Tea will cool at a constant rate, until it reaches the temperature of the environment (but it will not get any colder than this).
How does temperature affect the rate constant in a chemical reaction?
Temperature affects the rate constant in a chemical reaction by increasing it. As temperature rises, molecules move faster and collide more frequently, leading to a higher likelihood of successful reactions. This relationship is described by the Arrhenius equation, which shows that the rate constant is exponentially dependent on temperature.
