The linear form of the Arrhenius equation is very useful, as it allows us to calculate the ________ from the slope and the ________ from the intercept.

Question

Quizplus · Accepted Answer

The linear form of the Arrhenius equation is given by:
ln(k) = ln(A) - Ea/RT
where k is the rate constant, A is the pre-exponential factor or frequency factor, Ea is the activation energy, R is the gas constant, and T is the temperature in Kelvin.
Taking the natural logarithm of both sides of the equation results in a linear equation of the form y = mx + b, where y = ln(k), x = 1/T, m = -Ea/R, and b = ln(A).
Thus, the slope of the line is -Ea/R, from which the activation energy can be calculated, and the intercept is ln(A), from which the pre-exponential factor or frequency factor can be determined. Therefore, the correct answer is C) activation energy; frequency factor.
