Usually, increasing concentration of reactants increases the rate of reaction, but increasing concentrations of products reduces the rate of reaction. However, if one reactant is already present in large stoichiometric excess over another, increasing the concentration of that reactant may not increase the rate of reaction at all, and if the free energy of reaction is large enough in magnitude, increasing the concentration of products may not reduce the rate of reaction at all.
What else can I help you with?
How does an increase in temperatre affect chemical reaction?
Increases reaction rate.
What are the factors affecting the rates of chemical reaction in pollution?
The factors that affect in the rate of chemical reaction are temperature and YOU XD HAHAHAHAHAHAHAHA jk
How is a catalysts different from a reactant?
A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process, while a reactant is a substance that participates in a chemical reaction and is consumed. Essentially, a catalyst speeds up a reaction without being changed itself, while a reactant is consumed during the reaction.
What is the difference between rate of reaction and chemical equation?
The chemical equation is the word expression of a chemical reaction.The rate of reaction give information about the speed of this reaction.
What are situations that can effect the rate of a chemical reaction?
In a typical chemical reaction, xA + yB --> zC, the rate can be expressed as: Rate = k (T) * [A]^x * [B]^y where k = Rate constant, a function of temperature [i] = molar concentration of reagent i So, chemical reaction rate is affected by temperature and reagent concentration. Thus any variable that affects temperature (e.g. pressure or volume in the case of gases) will also affect reaction rate. However, the rate constant k is also a function of activation energy, the energy required to drive the reagents to the point where the reaction must proceed to completion. This activation energy can be lowered by the presence of a catalyst. Thus the presence of a catalyst can also affect the reaction rate.
How does an increase in temperatre affect chemical reaction?
Increases reaction rate.
How does concentration affect the rate of a chemical reaction?
Increasing the concentration of the reactants increases the rate of the reaction.
How do coefficients affect the rate law of a chemical reaction?
Coefficients in a chemical reaction affect the rate law by determining the order of the reaction with respect to each reactant. The coefficients indicate how many molecules of each reactant are involved in the reaction, which helps determine the overall rate of the reaction.
How does temperature affect the rate of a chemical change?
Changing temperatures has a dramatic affect on the rate of chemical reaction. As an example for every 10 degrees you raise the environment the reaction doubles (to a certain degree)
Do emzymes increase the rate of chemical reaction they affect?
That is precisely correct.
How does the amount of time given affect the rate of the enzymatic reaction?
it will increase the time of the chemical reaction
What are the factors affecting the rates of chemical reaction in pollution?
The factors that affect in the rate of chemical reaction are temperature and YOU XD HAHAHAHAHAHAHAHA jk
If the order of a chemical reaction with respect to one of its reactants is zero how does that reactant's concentration affect the rate of the chemical reaction?
If the order of a reactant is zero, its concentration will not affect the rate of the reaction. This means that changes in the concentration of the reactant will not change the rate at which the reaction proceeds. The rate of the reaction will only be influenced by the factors affecting the overall rate law of the reaction.
Why do solids not affect equilibrium in a chemical reaction?
Solids do not affect equilibrium in a chemical reaction because their concentration remains constant and does not change during the reaction. This means that the presence of solids does not impact the equilibrium position or the rate of the reaction.
Why catalyst affect the rate of chemical reaction?
They provide alternative pathway for the reaction, usually with less energy barrier
What factors influence the rate of a forward reaction in a chemical reaction?
The rate of a forward reaction in a chemical reaction is influenced by factors such as temperature, concentration of reactants, surface area, and the presence of catalysts. These factors can affect how quickly the reactants are converted into products.
What is the rate of chemical reaction is?
The rate of chemical reactions is how long a chemical reaction takes to finish.
