when temperature is raised ,the K.E. of molecules increases. Due to which molecules collide rapidly and consequently the rate of reaction increases. In other words: increasing the temperature increases both the rate at which collisions occur (because the molecules are moving around more) and the likelihood that the colliding molecules will react (because they're more likely to have sufficient kinetic energy to overcome the activation energy barrier).

What two factors speed up rates of chemical reaction and weathering?
Two factors that can speed up rates of chemical reaction and weathering are increased temperature and higher concentration of reactants or weathering agents. Higher temperature provides more energy for molecules to react, while increased concentration provides more opportunities for collisions between reactant molecules.
What temperature is the reaction at equilibrium?
The temperature at which a reaction reaches equilibrium can vary depending on the specific reaction and its conditions. For some reactions, the temperature at equilibrium may be higher, while for others it may be lower. The equilibrium temperature is determined by the enthalpy change of the reaction and the equilibrium constant.
What increases the rate of chemical weathering of rock?
Factors that can increase the rate of chemical weathering include a higher temperature (which accelerates chemical reactions), higher precipitation levels (which provide more water for chemical reactions), and the presence of acidic substances (such as acid rain or organic acids) that can speed up the breakdown of rock minerals.
What is a main reason that an increase in temperature increases the rate of a chemical reaction?
Temperature is the measure of the average kinetic energy of the molecules involved. If the temperature increases, then the kinetic energy of the molecules increases and they move faster. Faster moving molecules have more collisions with other molecules and more forcefully. For a reaction to occur, the molecules have to line up correctly and with adequate force. By increasing the speed of the particles, you are increasing the chance that the two molecules will align and produce a reaction.
What effects the rate constant of a reaction?
The temperature of the system
Why does thermal energy effect a chemical reaction?
Generally the reaction rate is higher at high temperature.
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.
Does temperature rising in a chemical mixer have to do anything with a chemical reaction?
Yes, a rise in temperature in a chemical mixer can influence the rate and extent of a chemical reaction. Increased temperature generally increases the kinetic energy of molecules, which can lead to more frequent collisions and higher chances of successful collisions between reactant molecules, thus speeding up the reaction. However, the specific effect of temperature on a reaction depends on the reaction kinetics and thermodynamics of the system.
What is the procedure to speed up a chemical reaction?
All C.R.'s speed up at higher temperature.
What is the relationship between temperature and the rate law of a chemical reaction?
The relationship between temperature and the rate law of a chemical reaction is that an increase in temperature generally leads to an increase in the rate of the reaction. This is because higher temperatures provide more energy for the reacting molecules to overcome the activation energy barrier, resulting in a faster reaction rate.
What change will most likely increase the rate of a chemical reaction?
Increasing the temperature of the reaction will most likely increase the rate of a chemical reaction. This is because higher temperatures provide more energy to the reactant molecules, allowing them to overcome the activation energy barrier and react more easily.
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.
Do chemical changes only happen at a heigh temperature?
No, chemical changes can occur at various temperatures depending on the specific reaction. While many chemical reactions do happen at higher temperatures to provide enough energy for the reaction to occur, there are also reactions that occur at lower temperatures. Temperature is just one factor that can influence the rate of a chemical reaction.
Heat is felt when a warm object is place in your hand chemical reaction?
The sensation of heat when holding a warm object is not caused by a chemical reaction, but rather by the transfer of thermal energy from the object to your hand. This transfer occurs through a process called conduction, where heat flows from the object's higher temperature to your hand's lower temperature.
Why does temperature affect the rate sodium thiosulphate and hydrocholric acid react?
Temperature affects the rate of reaction between sodium thiosulfate and hydrochloric acid by increasing the kinetic energy of the particles involved. This leads to more frequent and energetic collisions between the reactant molecules, increasing the likelihood of successful collisions and hence speeding up the reaction rate. Additionally, higher temperatures can also alter the activation energy required for the reaction to occur, further influencing the reaction rate.
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.
