Explanation / Answer

We need to plot lnK on y axis and 1/T on x axis
K = 0.399
ln K = ln (0.399) = -0.91879
T = 275.0
1/T = 0.00364


point 1 is:
x = 0.00364
y = -0.91879


K = 0.722
ln K = ln (0.722) = -0.32573
T = 525.0
1/T = 0.0019


point 2 is:
x = 0.0019
y = -0.32573


----------------------------------------------------------------------------
rise = (y1-y2) = -0.91879 - -0.32573 = -0.59306
rise = (X1-X2) = 0.00364 - 0.0019 = 0.00173
slope = rise/run
= -0.59306/0.00173
= -342.4943
----------------------------------------------------------------------------
use
slope = - Ea/R
= -342.4943 = -Ea/8.314
Ea = 2847 J/mol
Answer: 2847 J/mol
