There are three things needed for combustion: heat, oxygen, and fuel. After the reaction has started, the production of heat may fuel the reaction, making it self sustaining.

Why does a catalyst speed up the rate of reaction?
The use of a catalyst increases the chance of particles meeting. This causes there to be a decrease in activation energy, and results in an increase in rate of reaction.
The process of rapid combustion?
A combustion reaction which takes place at a high speed and with the release of a huge amount of heat and light is known as rapid combustion.
What it will change adding a catalyst to a chemical reaction?
It will increase or decrease the speed of the chemical reaction.
What will change when a catalyst is added to a chemical reaction?
A catalyst speeds up the rate of reaction, and lower the activation energy needed.
How does a catalyst speed a reaction at low temperature?
A catalyst reduces the amount of energy required to produce the reaction. This speeds up the reaction and causes it to finish more quickly. Raising the temperature will also speed up a reaction.
How does average particle speed affect the reaction rate?
As the speed of the particles increase, it causes them to collide with the other particles in which they are reacting with more frequently, increasing the reaction rate.

What is the effect of increasing the concentration of enzymes in a reaction?
If the reaction speed has not already peaked, then it will increase

How does a enzyme increase the speed of a reaction?
The enzyme reduces the activation energy of the reaction, therefore chemical reaction speeds are increased.
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.
What a 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.
Why does the amount of denitration increase at high temperatures?
- the speed of reaction increase with increasing temperature - the actual efficiency increase with increasing temperature
Does the core cause a huge increase in the speed of P-waves?
No, it causes a huge decrease in speed.
What increases the reaction rate by increasing particle speed?
An increase in temperature will increase the speed of the particles and cause the particles to both bump into one another more frequently and with more energy thus increasing the reaction rate.
