To determine the rate constant of a reaction, you need to know the rate equation and the concentrations of the reactants involved. The rate constant (k) can be calculated using the formula: rate = k [A]^m [B]^n, where [A] and [B] are the concentrations of the reactants and m and n are their respective reaction orders. If the rate is 0.2, you'll need the concentrations and reaction orders to find k. Without that information, the rate constant cannot be determined.

What is the k in the rate law equation?
A rate constant
What is the rate constant when a first-order reaction is 35.5 percent complete in 4.90 minutes at 25 degrees celsius?
To calculate the rate constant for a first-order reaction, you can use the natural logarithm function. Rearrange the integrated rate law for a first-order reaction to solve for the rate constant. In this case, k = ln(2)/(t(1/2)), where t(1/2) is the half-life of the reaction. Given that the reaction is 35.5% complete in 4.90 minutes, you can use this information to find the half-life and subsequently calculate the rate constant.
How can rate constant be determined from the rate law?
The rate constant is the reaction rate divided by the concentration terms.
What is The order of reaction for which unit of rate and rate constant is same?
In a zero order overall process, the rate and rate constant will be the same. (Reaction order is an exponent, and if that exponent is "0" then the value is "1" and will cancel out.)
What do you mean by specific reaction rate of a reaction?
The rate constant include all parameters ((but not concentration) affecting the rate of a chemical reaction.The expression "specific reaction rate" is used when the molar concentration of reactants is a unit.
What is the value and unit of the rate constant for this reaction?
The value and unit of the rate constant for a reaction represent how fast the reaction occurs. The rate constant is typically denoted by the symbol "k" and its unit depends on the overall order of the reaction. The unit of the rate constant can be determined by the reaction rate equation.
What is the rate constant for this zero-order reaction?
The rate constant for a zero-order reaction is a constant value that represents the rate at which the reaction proceeds, regardless of the concentration of reactants.
What is the k in the rate law equation?
A rate constant
What is the rate constant for this first-order reaction?
The rate constant for a first-order reaction is a constant value that determines how quickly the reaction occurs. It is denoted by the symbol "k" and is specific to each reaction. The rate constant can be calculated by using experimental data from the reaction.
What is the zero order reaction rate law and how does it determine the rate of a chemical reaction?
The zero order reaction rate law states that the rate of a chemical reaction is independent of the concentration of the reactants. This means that the rate of the reaction remains constant over time. The rate of the reaction is determined solely by the rate constant, which is specific to each reaction. This rate law is expressed as: Rate k, where k is the rate constant.
In what ways do reaction rate, rate law, and rate constant differ in chemical kinetics?
In chemical kinetics, reaction rate refers to how fast a reaction occurs, rate law is the mathematical expression that relates the reaction rate to the concentrations of reactants, and rate constant is a constant value that represents the speed of the reaction at a specific temperature.
How can the rate constant be determined from the rate law?
The rate constant is the reaction rate divided by the concentration terms.
What is relative rate constant?
The relative rate constant is a ratio of the rate constants of two reactions in a chemical reaction mechanism. It is used to determine the rate of reaction between different reactants in relation to each other.
How can one determine the rate constant in a chemical reaction?
The rate constant in a chemical reaction can be determined by conducting experiments and measuring the reaction rate at different concentrations of reactants. By plotting the data and using the rate equation, the rate constant can be calculated.

Does the rate constant change with concentration in a chemical reaction?
Yes, the rate constant can change with concentration in a chemical reaction.
