What is the slope of an arrhenius plot for the following reaction? 2nocl → 2no + cl 2 picture

a. 8.18 × 10−2 k
b. 5.06 × 10−2 k
c. −1.22 × 104 k
d. −1.96 × 104 k
e. not enough information to calculate the slope

c. −1.22 × 10^4 K

Explanation:

Generally, the slope of an Arrhenius plot can be determined either from the graph of In k against 1/T or the available experimental data of the rate constant (k) and the absolute temperature. Mathematically,

Where:

L/(mol.s)

L/(mol.s)

K

K

slope = (ln 2.9*10^-1 - ln 6.6*10^-4)/(1/500 - 1/400)

slope = (-1.238+7.323)/(0.002-0.0025)

slope = 6.085/-0.0005 = -1.22*10^4 K
