Ignition temperature is the temperature a substance needs to reach before it is combustible. Activation energy is the energy required to start a reaction occurring. Temperature is directly affected by heat. Heat is a form of energy. Therefore as you add energy to a substance it heats up. It will reach its ignition temperature and combust. The combustion is the reaction.

∙ 12y agoTemperature increases the reaction rate constant 'k'. This is done by increasing the energy of the reactants which makes it easier for them to overcome the energy barrier needed for a reaction. Of course increasing the temperature will increase the rate of reaction of an endothermic reaction but will limit the speed of an exothermic reaction

What leads to an increase in the rate of a chemical reaction?
Either (or both) an increase in the reactants or temperature will increase the rate of a chemical reaction.
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.
How do changes in temperature and energy influence chemical changes?
The reaction rate is dependent on temperature (increasing the temperature the reaction rate increase) and activation energy.
An increase in temperature will cause the rate of a chemical reaction to?
Increasing the temperature the dissolving rate increase.
How does increasing the temperature effect a chemical reaction?
Raising the temperature makes chemical reactions faster.
How are temperature and the Arrhenius theory related?
The reaction rate of a chemical reaction is dependent on temperature.

What do concentration surface area and temperature have in common?
They can all affect the rate of a chemical reaction.
Does temperature effect the rate of chemical reaction?
yes.

Increasing the temperature the dissolving rate increase.
How does increasing the temperature effect a chemical reaction?
Raising the temperature makes chemical reactions faster.
Does the change of temperature will slow or faster the chemical reaction?
No, an increase in temperature will speed up the reaction. This is because the heat energy is transferred into kinetic energy (movement energy) in the reactors and this increases their speed and so increases the rate at which they collide with each other, increasing the rate of the chemical reaction.
Why does thermal energy effect a chemical reaction?
Generally the reaction rate is higher at high temperature.
Is the rate of a chemical reaction dependent of temperature?
In general, as temperature rises, so does reaction rate. This is because the rate of reaction is dependent on the collision of the reacting molecules or atoms. As temperature rises, molecules or atoms respond with increased motion, increasing the collision rate, thus increasing the reaction rate.
