Question

A)Use and arthenius plot to determine the activation barrier for the reaction,

B)Use an Arthenius plot to determine frequency factor for the reaction.

The following data shows the rate constant of a reaction measured at several different temperatures. Use an Arrhenius plot to determine the activation barrier for the reaction. Express your answer using three significant figures. Use an Arrhenius plot to determine frequency factor for the reaction. Express your answer using two significant figures.

Explanation / Answer

1) logk2/k1 = Ea/2.303R[1/T1-1/T2]

log(0.495/0.186 )= Ea/2.303*8.314[1/320-1/330]

Ea = 85951.02 j

Ea = 85.951kj

2)
logk = log A -Ea/(2.303RT)

log(2.15*10^-2) = logA -85951.02/(2.303*8.314*300)

A= 1995262314968.8 sec^-1
