What else can I help you with?
Which methods will usually cause a reaction to speed up?
Combining the reactants at a lower temperature. Reducing the concentration of reactants. Grinding one of the reactants into a powder. Removing the catalyst.
What factors affect the rate of a chemical reaction?
Temperature of system (molecular vibrational speed), Pressure of system (proximity), Catalysts (lowers activation energy of reaction), Volume of vessel (related to pressure), and Concentration of reagents (more collisions).
What would cause entropy to decrease in a reaction?
The products becoming more ordered than the reactants
What direction doe the equilibrium shift when reactants are added to it?
Adding reactants to an equilibrium mixture will cause the equilibrium to shift to the right in order to consume the excess reactants. This helps restore the equilibrium conditions by favoring the forward reaction to produce more products.
What would cause entropy to increase in reaction?
The products becoming more spread out.

What Conditions Cause A Reaction To Occur?
A reaction occurs when reactants come into contact with each other and have sufficient energy to overcome the activation energy barrier. Factors that can affect the likelihood of a reaction include concentration, temperature, pressure, and the presence of a catalyst.

Temperature of system (molecular vibrational speed), Pressure of system (proximity), Catalysts (lowers activation energy of reaction), Volume of vessel (related to pressure), and Concentration of reagents (more collisions).
When after a chemical reaction do the reactants still exist?
There can be many cases. One of them being that you take the reactants in excess then a little portion of the reactants remain. Another is the reaction cannot take place. In reversible reactions. But you should note that the exact proportion of reaction cannot remain in a reaction cause you are trying to form new comounds during this reaction.
What causes an increase of speed in a combustion reaction?
An increase in temperature, pressure, or concentration of reactants can cause an increase in speed in a combustion reaction. This provides more energy to break the bonds and allows the reaction to proceed faster.
What are four ways that Chemists can't control their rates of chemical reactions?
Chemists cannot control reaction rates through factors such as temperature fluctuations, which can lead to unpredictable kinetic energy changes. Additionally, variations in concentration of reactants can cause inconsistencies in reaction speed. The presence of impurities or catalysts can also alter reaction dynamics in unforeseen ways. Lastly, external conditions like pressure changes, particularly in gaseous reactions, can unpredictably affect the rate of reaction.
What would cause the greatest decrease in the rate of chemical reaction?
For most reactions, the lowering of the temperature of the reactants.
What would cause entropy to decrease in a reaction?
The products becoming more ordered than the reactants
In the reaction 2SO2 plus O2 Reversible 2SO3 which change would cause the greatest increase in the concentration of SO3?
Increasing the concentration of either SO2 or O2 would drive the reaction towards the formation of more SO3, resulting in an increase in the concentration of SO3. Increasing the temperature, however, would cause the greatest increase in the concentration of SO3 as it favors the forward reaction which produces more SO3.
What cause entropy to decrease in a reaction?
The products becoming more ordered than the reactants
What effect does the addition of NaOH have on the concentration of H?
say for example the equilibrium I2(aq)+H2O(l)-----HOI(aq)+I(aq)+H(aq) Think Lechatlier principle... addition of NaOH will cause the H ions to react with the OH ions to cause more water (more reactants) increase in reactants shifts the equilibrium in the FORWARD direction to form MORE H+ to restore the equilibrium
Does loud music affect your concentration?
I think loud music doesn't affect your concentration. In some cases the rhythm of the music can cause a certain concentration. Then the way you remember the music you'll be able to remember what you were doing.
