Map Sapling Learning macmillan learning If you were going to graphically determine the activation energy of this reaction, what points would you plot? Consider this reaction data A products Number Number T (K) k (s) 275 525 point 1 To avoid rounding errors, use at least hree signiticant figures in all values 0.385 0.664 Number Number point 2 Determine the rise, run, and slope of the line formed by these points rise run slope Number Number Number What is the activation energy of this reaction? Number J/ mol

Explanation / Answer

We need to plot lnK on y axis and 1/T on x axis
k = 0.385
ln k = ln (0.385) = -0.95451
T = 225.0
1/T = 0.00444


point 1 is:
x = 0.00444
y = -0.95451


k = 0.664
ln k = ln (0.664) = -0.40947
T = 525.0
1/T = 0.0019


point 2 is:
x = 0.0019
y = -0.40947


----------------------------------------------------------------------------
rise = (y1-y2) = -0.95451 - -0.40947 = -0.54504
rise = (X1-X2) = 0.00444 - 0.0019 = 0.00254
slope = rise/run
= -0.54504/0.00254
= -214.60903
----------------------------------------------------------------------------
use
slope = - Ea/R
= -214.60903 = -Ea/8.314
Ea = 1784 J/mol
Answer: 1784 J/mol
