What is relative rate constant?
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 has the largest rate constant k?
exploding dynamite
1 Write down the relation between the rate constant and the temperature of a?
Here it is in two forms: k = A exp (-Ea/RT) ln k = ln A - Ea/RT The latter is a linearized version. In both cases... k is the rate constant, A is the frequency factor (an experimentally determined quantity related to the probability that a collision will lead to a reaction), Ea is the activation energy, R is the Universal Gas constant (8.31 J/mol K), and T is the temperature in Kelvins.
How can the rate constant be determined from the rate law?
The rate constant is the reaction rate divided by the concentration terms.
What equation shows how rate depends on concentrations of reactions?
The equation is called the rate law equation. For the reaction aA+bB =>cC+dD the rate law would be rate = k[A]^m[B]^n where k is the rate constant and m and n are the "order" with respect to each reactant. m and n must be determined experimentally and may or may not be the same as the coefficients a and b.
What has the smallest constant rate k?
chemical changes causing leaves to brown in the fall
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 relative rate constant?
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.
Which has the largest rate constant k?
Dynamite exploding
What has the largest rate constant k?
exploding dynamite
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 smallest rate constant?
chemical changes causing leaves to brown in the fall
What has the largest value of the constant k?
how does the rate law show how concentration changes after the rate of reaction
which equations would be used to calculate the rate constant from initial concentrations?
k=Rate/[A^m][B^n]
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 a constant K formula?
K = constant
