What happens to the rate constant of a chemical reaction when the temperature increases?
The rate constant of a chemical reaction generally increases with temperature due to the higher kinetic energy of the reactant molecules, resulting in more collisions and successful reactions occurring at a faster rate with increased temperature. This relationship is described by the Arrhenius equation.
What a does a temperature increase cause the rate of a reaction to increase?
An increase in temperature typically causes the rate of a reaction to increase because it provides more energy to reactant molecules, allowing them to collide with greater force and frequency. This often leads to more successful collisions and faster conversion of reactants to products.
How does a temperature increase cause the rate of a reaction rate to increase?
It increases the kinetic energy of the molecules (APEX)
What would cause entropy cause in a reaction?
The products becoming more spread out.
How does a temperature increase cause the rate of a reaction to increase increase?
It increases the kinetic energy of the molecules (APEX)
Why does a change in body temperature indicate that a chemical reaction may have occurred?
A change in body temperature can indicate a chemical reaction because most chemical reactions involve the absorption or release of energy in the form of heat. If the reaction absorbs heat from the surroundings, it can cause a decrease in temperature, while if it releases heat, it can cause an increase in temperature. Monitoring changes in body temperature helps to detect and analyze chemical reactions.

How does temperature increase cause the rate of reaction to increase?
The movement of molecules and collisions are increased at high temperature.
What does a temperature increase cause the rate of a reaction to increase?
As temperature increase the speed and energy of molecules increase and the collisions are more probable.
How does temperature increase cause the rate of a reaction to increase?
It increases the kinetic energy of the molecules (APEX)
What are two variables that would cause a chemical reaction to have a fast reaction rate?
Increased concentration, increased temperature, and a catalyst will all increase reaction rates relative to what they normally are. Some reactions however will still be slow even with the change in these variables.
How does temperature affects the order of a reaction?
An increase in temperature usually increases the rate of a reaction by providing more kinetic energy to the reactant molecules, which leads to more frequent and energetic collisions. This can often decrease the order of the reaction because the rate constant (k) usually increases with temperature, making the reaction appear to proceed faster and with a lower order.
What would cause the greatest decrease in the rate of chemical reaction?
For most reactions, the lowering of the temperature of the reactants.

Do heating matter increases its mass?
When you heat matter, it does not increase its mass. Heating matter can cause changes in temperature, density, and volume, but mass remains constant unless there is a chemical reaction or nuclear process involved.
What Three Things can happen when a Chemical Reaction occur?
A chemical reaction can change a substance into a solid, liquid, or gas. It may cause a substance to explode or could cause no change at all.
Does a chemical reaction cause chemical changes?
yes
