Will affect the rate of the constant according to the Arrhenius equation changing which factors?
Temperature and activation energy
What is an Arrhenius equation?
An Arrhenius equation is an equation which approximates the dependence of the rate of any chemical reaction on the temperature.
Is rate constant equal to one over TIME in the Arrhenius Equation If so or not is there an equation representing their relationship?
The unit of the rate constant in a 1st Order reaction rate equation (NOT the 'Arrhenius equation', as stated in the question) is One over Time.General form of a reaction rate equation :rate (mol.L-1.time-1) = [rate constant(Ln-1.mol1-n.time-1)]*[Concentration()]nwhere:* n is the Order of the rate equation (that is of the rate limiting step) * all units are (italicalised) between brackets It can easily be seen in this that for n=1 (1st Order) the equation is:r = k * C1and in units:mol.L-1.time-1 = (L0.mol0.time-1)*(mol.L-1)1so:(mol.L-1.time-1) = (time-1)*(mol.L-1)Only the value of the rate constant k is depending on temperature only (cf. Arrhenius equation), though temperature is NOT in its unit.
What equation best describes an Arrhenius acid base reaction?
This is a neutralization reaction.
What can the effect of heat on a reaction be determined?
This effect is determined by experiments. Also Arrhenius equation can be used for a calculus.

Who created the Arrhenius equation?
The Arrhenius equation was created by Svante Arrhenius in 1889, based on the work of Dutch chemist J. H. van't Hoff. The rate equation shows the effect of changing the concentrations of the reactants on the rate of the reaction.
What is an Arrhenius equation?
An Arrhenius equation is an equation which approximates the dependence of the rate of any chemical reaction on the temperature.
Does the temperature have to be in Kelvin for the Arrhenius equation?
Yes, since the R constant has units of Latm/molK, temperature must be in K
What is the connection between accelerated aging test of a material and Arrhenius equation?
The Arrhenius equation is a formula for the dependence of reaction rates on temperature. The accelerated aging test of a material depends on the Arrhenius equation for it to work.
How do you determine Ea by Arrhenius equation?
yes

Arrhenius equation), though temperature is NOT in its unit.
What relationship is described by the Arrhenius equation?
The Arrhenius equation describes a number of temperature dependent chemical reactions. These comprise not just the forward and reverse reactions, but also other reactions that are thermally influenced such as diffusion processes.
What equation best describes an Arrhenius acid base reaction?
This is a neutralization reaction.
What is the Arrhenius equation?
It is an equation that relates the speed at which a chemical reaction progresses with the activation energy and the temperature of the reactants and products. k = A * e^(-Ea/(R*T)) Where k = velocity constant (different for each reaction) A = pre-exponential factor Ea = activation energy R = universal gas constant (=8,314J/molK) T = temperature
What can the effect of heat on a reaction be determined?
This effect is determined by experiments. Also Arrhenius equation can be used for a calculus.
If HCL and Na2S2O3 are kept constant by how many degrees would this reaction have to be heated from 25 degrees C to precisely double the reaction rate?
You need to use the Arrhenius equation to solve this kind of problem. Since you haven't given the activation energy, we can't answer it for you.
