The **Arrhenius equation** is often written as:

#ln(k_2/k_1) = -E_a/R[1/T_2 - 1/T_1]# #" "" "bb((1))#

or

#overbrace(lnk)^(y) = overbrace(-E_a/(R))^(m) overbrace(1/T)^(x) + overbrace(ln A)^(b)# #" "" "bb((2))#

for practical use, but tends to be introduced as

#k = Ae^(-E_a"/"RT)# .#" "" "bb((3))#

Generally, the rate constant for multiple temperatures of the same reaction is plotted against

The frequency factor
