What is Arrhenius model?
The Arrhenius model is used to describe the rate of a chemical reaction as a function of temperature. It states that the rate constant of a reaction increases exponentially with an increase in temperature, according to the equation k = A * e^(-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.
How do you rearrange the Arrhenius equation in terms of temperature?
To rearrange the Arrhenius equation in terms of temperature, you need to isolate the temperature term. Start by taking the natural logarithm of both sides and then rearrange the equation to solve for temperature. The resulting equation will show temperature as a function of the rate constant, activation energy, and frequency factor.
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.
