### Slope of Arrhenius Plot

Why is the slope equal to -activation energy/R? How does that make sense with respect to the plot?

The Arrhenius equation: ln k = -Ea/RT + ln A

Plot: ln k vs 1/T

Therefore, slope = -Ea/R

Will the slope always be negative?

Yes, the slope will always be negative because activation energy is always a positive value.

I mentioned this in class a couple of times: activation energies and rate constants are always positive values
