What would most likely result in the greatest decrease in the rate of a chemical reaction?
what would most likely result in the greatest decrease in the rate of a chemical reaction
A factor that slows down a chemical reaction?
A decrease in temperature.
Does every collision between reacting particles leads to products?
For a reaction to take place, the reactants must have sufficient energy and have correct orientation when they collide. So, the reason why all collisions don't lead to reaction is that the collisions do not satisfy these conditions.
Does energy decrease or increase during a chemical reaction?
Energy is only made not taken away. But during a chemical reaction, it depends on what kind of chemicals you put in there.
Why does an increase reaction temperature generally increase the reaction rate?
All chemical reactions must be thought of as collisions between the particles of reactants and products. As the temperature of the reaction increases, the energy of the particles also increases and so there is a greater chance of more collisions occuring, and as a result, in general, an increase in reaction temperature increases the reaction rate
What is the effect of a catalyst on the required energy to achieve effective collisions?
catalyst decreases the activation energy of a chemical reaction, thereby increasing the effective collisions and hence the rate of the chemical reaction
If the activation energy is increased what happens to the number of effective collisions?
The probability that a chemical reaction to occur increases.
IS it true that enzymes increase the number of collisions in a chemical reaction?
No that is false. Enzymes do NOT increase number of collisions in a chemical reaction.
Which factor can decrease the rate of a chemical reaction?
concentration of product. concentration of poisons.
How does the catalyst and inhibitors affect the rate of chemical reaction?
Catalyst ensures that the activation energy of the molecules is lowered so there is effective collisions,and it does this in two ways;the transition and absorbtion states but inibitors even raises the activation energy and causes in effective collisions.
As temperature decreases the rate of an enzyme-catalyzed reaction also decreases why?
Just like many other chemical reactions, the rate of an enzyme-catalyzed reaction will decrease with temperature because of the decrease in the number of high energy collisions between particles.
According to collision theory increasing the concentration of the reactants in a chemical reaction increases?
A.the rate of collisions between two particles.
What will higher temperatures do in a chemical reaction?
Higher temperature is responsible for higher kinetic energy of molecules therefore higher no of effective collisions among the reacting molecules and therefore higher rate of reaction.
Adding a catalyst increases reaction speed by?
Catalysts lower the activation energy required for a chemical reaction. Activation energy refers to the mininum amount of energy that the reactant particles must possess so that effective collisions between them (hence a chemical reaction) can occur.
What it will change adding a catalyst to a chemical reaction?
It will increase or decrease the speed of the chemical reaction.
Do Enzymes increase or decrease the Activation Energy of a Chemical Reaction?
decrease
What would most likely result in the greatest decrease in the rate of a chemical reaction?
what would most likely result in the greatest decrease in the rate of a chemical reaction
