The activation energy of a reaction is given by
A) +(slope of a plot of lnk vs 1/T) / R.
B) -(slope of a plot of lnk vs 1/T) / R.
C) -R / (slope of a plot of lnk vs 1/T).
D) +(slope of a plot of lnk vs 1/T) * R.
E) -(slope of a plot of lnk vs 1/T) * R.

Question

Quizplus · Accepted Answer

The activation energy (Ea) is determined from the Arrhenius equation, where the slope of a plot of ln(k) versus 1/T is equal to -Ea/R. Therefore, Ea = -(slope) * R.
