## Arrhenius Equation

$aR \to bP, Rate = -\frac{1}{a} \frac{d[R]}{dt} = \frac{1}{b}\frac{d[P]}{dt}$

### Arrhenius Equation

What would be a situation in which to use the arrhenius equation? Is it just to plot ln K vs 1/T?

### Re: Arrhenius Equation

You can use the Arrhenius equation to find the activation energy as well as the rate constant at different temperatures.

### Re: Arrhenius Equation

The Arrhenius equation allows us to model how temperature affects the rate constant of a certain reaction. If the reaction can be modeled by it, the plot of ln(k) vs. 1/T will be linear.

### Re: Arrhenius Equation

The Arrhenius Equation is k=Ae^Ea/RT. We would use the arrhenius equation when you want to show the effect of changing the temperature on the rate constant. The arrhenius equation shows the relationship between the rate constant, k, temperature T, activation energy, and A, which is the proportionality constant/pre-exponential factor--which includes the # collisions with correct orientations.
