Rafa(Explanation): paper burns quickly, which is why it is often used to start fires. because the reaction happens quickly, the rate constant k is very high, especially compared with iron rusting or milk spoiling which take weeks to occur.

Which has the largest rate constant k?
Dynamite exploding
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 constant rate?
A relative rate constant the rate at which a reaction will take place. Ex. V = k [A][B] the constant ,k, is a constant value for the rate of the reaction in said equation.
What is the equation of an inverse relationship?
The equation is xy = k where k is the constant of variation. It can also be expressed y = k over x where k is the constant of variation.
What is the constant k in directs and inverse equations?
The constant could be any number.
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 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 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.
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?
A rate constant
What is the rate constant for a 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. It is typically denoted as "k" and has units of concentration/time.
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.
How can one determine the rate constant k in a chemical reaction?
The rate constant k in a chemical reaction can be determined by conducting experiments to measure the reaction rate at different concentrations of reactants. By plotting the data and using the rate equation, the rate constant k can be calculated.
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.
On what factors is the rate constant k dependent?
The rate constant k is dependent on factors such as temperature, concentration of reactants, presence of catalysts, and the nature of the reaction mechanism.
