Question

In chemical kinetics, the magnitude of the rate constant depends on: I. the reaction time of the chemical reaction II. the activation energy of the chemical reaction III. the wavelength that is set to monitor the chemical reaction IV. the concentration of the reactants used in the chemical reaction V. the temperature at which the chemical reaction is being conducted?

Answer 1

Answer:

THE TEMPERATURE AT WHICH THE CHEMICAL REACTION IS BEING CONDUCTED.

Explanation:

The reaction rate constant is dependence on the temperature in which the reaction takes place. The rate of a reaction and the activation energy relationship is given by the Arrhenius equation with the rate constant as a function of temperature.

Mathematically, the rate constant is expressed as;

k(T) = Ae^-Ea/RT

where Ea is the activation energy, R is the gas constant, Ae is the pre-exponential factor and it is the frequency at which a reactant molecule collide with each other, T is the temperature.
