New cards

what is on the x axis of the graph to calculate activation energy

1/T measured in K-1

2
New cards

what is on the y axis

lnk (k as rate constant)

3
New cards

what is the gradient of the line

-Ea/R

4
New cards

from the gradient how do we calculate the activation energy

Ea = -gradient x R

5
New cards

how do we calculate A from the graph

use the log form of the Arrhenius equation and points from the graph
