Answer:

The Arrhenius equation provides a relationship between the rate constant #k# and temperature #T#.

Explanation:

The Arrhenius equation provides a relationship between the rate constant #k# and temperature #T#.

The Arrhenius equation is: #k=zpe^(-(Ea)/(RT))#

where,
#k# is the rate constant,
#z# is the collision factor,
#p# is the steric factor,
#Ea# is the activation energy,
#R=8.3245J/(mol.K)# is the ideal gas constant
and #T# is the temperature.

The Arrhenius equation could also be written as: #k=Ae^(-(Ea)/(RT))#,

where, #A=zp# is the Arrhenius factor.

Taking the natural logarithm of both parties, we get:

#lnk=-(Ea)/R(1/T)+lnA#
