What factors affect the rate constant k?
The rate constant is directly proportional to the concentration of any given reactant. If the concentrations of the reactants increase, the rate constant increases. If the concentrations of the reactants decrease, the rate constant increases.
Is rate constant k dependent on concentration?
The rate law for a chemical reaction is the reaction between the rate of the chemical reaction and the reactant concentration. The constant of proportionality in the rate law is called the rate constant. The rate constant does not depend on the concentration.
What does the equilibrium constant k depend on?
The concentration of the products.
What does reaction rate constant depend on?
Rate constant of a reaction depends on its temperature only and not affected by concentration.
Does rate constant depend on catalyst?
→ It is independent of concentration but depends on temperature of the reaction, catalyst and activation energy.
Is K depend on initial concentrations?
Keq DOES NOT DEPEND ON INITIAL CONCENTRATIONS OF REACTANTS AND PRODUCTS (ALTHOUGH ABSOLUTE AMOUNT OF REACTANTS OR PRODUCTS AT EQUILIBRIUM DOES).
Why is K dependent on temperature?
Increasing the temperature of a reaction generally speeds up the process (increases the rate) because the rate constant increases according to the Arrhenius Equation. As T increases, the value of the exponential part of the equation becomes less negative thus increasing the value of k.
Does K depend on initial concentrations?
On which factor rate constant of a reaction does not depend upon?
Explanation: the rate constant of reaction does not depend on concentration of reactant & product (only on nature of reactant & product).
Does rate constant depend on order of reaction?
The units of the rate constant depend on the order of reaction. The rate constant isn’t a true constant, since its value depends on temperature and other factors.
What is rate constant K?
The specific rate constant (k) is the proportionality constant relating the rate of the reaction to the concentrations of reactants. The rate law and the specific rate constant for any chemical reaction must be determined experimentally. The value of the rate constant is temperature dependent.
Do rate constant depends on catalyst?
Yes, it does. The mechanism of a reaction can be altered by a catalyst. The arhennius equation shows that the rate constant will be greater for the catalysed reaction at any given temperature.
On which factor the rate constant of reaction does not depend on?
Does catalyst affect rate constant k?
Rate constant, is unaffected by catalysts. This is because the rate of the forward reaction is changed as much as the rate of the reverse reaction.
How do you find the rate constant K?
To find the rate constant:
- Determine how many atoms are involved in the elementary step of the reaction.
- Find out the order of reaction for each atom involved in the reaction.
- Raise the initial concentration of each reactant to its order of reaction, then multiply them all together.
What is the value of constant K?
The Coulomb constant, the electric force constant or the electrostatic constant which is denoted by k or K is a proportionality constant in electrostatics equations. The value of K in SI units is equal to 8.98755 × 109 kg. m3.
Is rate constant dependent on temperature?
Temperature Dependence of the Rate Constant: Increasing the temperature of a reaction generally speeds up the process (increases the rate) because the rate constant increases according to the Arrhenius Equation.
