Rate of reactions?
The rate of a reaction is the time it takes for a reaction to take place. The rate of reactions can be affect by different factors such as the temperature, the air pressure, the concentration of each substance and whether a catalyst is used (a catalyst is something that lowers something's activation energy so the reactants have more energy to react). A reaction happens when atoms collide with each with a big enough force therefore a bigger surface area would help speed this up. Also the amount of energy the particle/atoms have helps. With these factors you can determine the speed at which a reation happens. Any questions?
What happens to the rate constant of a chemical reaction when the temperature increases?
Increasing the temperature will cause there to be an increase in kinetic energy. This results in an increase in collision frequency, and eventually an increase in rate of reaction as well.
What happens to the entropy in the reaction I2s I2g?
Entropy increases in the reaction.
What happens to the entropy in the reaction I2 s I2 g?
Entropy increases in the reaction.
What happens to the reaction as a reactant gets used up?
It slows and then stops.
What are three factors of the speed at which a chemical reaction happens?
temperature presence or absence of a catalyst concentration of reactants

What is the difference between normal reaction and abnormal reaction?
Normal reaction happens when the reaction is normal. Abnormal reaction happens when the reaction is abnormal.
What happens to catalyst used in a reaction?
It is unchanged by the reaction.
What happens to the rate constant of a chemical reaction when the temperature increases?
Increasing the temperature will cause there to be an increase in kinetic energy. This results in an increase in collision frequency, and eventually an increase in rate of reaction as well.
What happens when a nonmetal and a nonmetal bond?
a reaction happens
What reaction happens when you combine two elements?
A synthesis reaction.
In a enzyme reaction is exposed to an unfavorable pH what happens to the speed of the reaction?
catalyzed reaction
What happens to the reaction rate when a catalyst is used in a chemical reaction?
With a catalyst the reaction rate is higher.
What happens to the entropy in the reaction I2s I2g?
Entropy increases in the reaction.
What type of chemical reaction happens when wax burns?
This is an oxydation reaction.
What happens after equilibrium?
Rate of forward reaction=rate of backward reaction
