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.
Which has the smallest rate constant k?

1 Write down the relation between the rate constant and the temperature of a?
The rate constant of a reaction generally increases with temperature, following the Arrhenius equation: k = Ae^(-Ea/RT), where k is the rate constant, A is the pre-exponential factor, Ea is the activation energy, R is the gas constant, and T is the temperature in Kelvin. Rise in temperature leads to more collisions and higher energy to overcome activation energy barrier, resulting in faster reaction rates.
A first order reaction is found to have a rate constant t k equals .0000739 find the half life of this reaction?
To solve for the half-life of a first-order reaction, you can use the equation t1/2 = 0.693/k, where k is the rate constant. Plugging in the given rate constant of 0.0000739, you get t1/2 = 0.693 / 0.0000739 = 9376.63 seconds. Therefore, the half-life of this reaction is approximately 9376.63 seconds.
Is rate constant equal to one over TIME in the Arrhenius Equation If so or not is there an equation representing their relationship?
In the Arrhenius equation, the rate constant (k) is not equal to one over time. The rate constant is a specific rate of reaction at a given temperature and is related to the activation energy (Ea) and the temperature (T) through the equation k = A * e^(-Ea/RT), where A is the pre-exponential factor and R is the gas constant. The relationship between rate constant (k) and time is more complex and depends on the reaction mechanism and conditions.
Which has the largest rate constant k?
Dynamite exploding
What has the largest values of the rate constant k?
how does the rate law show how concentration changes after the rate of reaction
What has the largest value of the constant k?
how does the rate law show how concentration changes after the rate of reaction
What is an apparent rate constant?
First order rate constant k is described in V=k[EA] while second order rate constant is given as V=k[E][A]. For reactions that do not have true order, k is the apparent rate constant.
What is the k in the rate law equation?

Why is it necessary to specify the temperature when giving a value for k?
The rate constant (k) of a reaction is temperature-dependent according to the Arrhenius equation. Therefore, specifying the temperature is necessary to accurately determine the rate constant and predict the reaction rate at that specific temperature. Changes in temperature can significantly influence the rate constant and overall reaction kinetics.
which equations would be used to calculate the rate constant from initial concentrations?
k=Rate/[A^m][B^n]
