Question:
The activation energy of a reaction can be determined from the slope of which of the following graphs?
ln K vs.1/T
TlnK vs.1/T
ln K vs. T
lnKT vs.T
Solution:
The Arrhenius equation is lnK = lnA − Ea/RT. Thus, the activation energy of a reaction can be determined from the slope of the graph ln K vs. 1/T. Slope = −Ea/R. Hence, Ea = −slope × R
