What is the slope of a plot of ln k vs. 1/T for the Arrhenius equation k = Ae^-(^E_a/RT)?

Question

Quizplus · Accepted Answer

The Arrhenius equation is given by ln k = ln A - (Ea/RT), where Ea is the activation energy and R is the gas constant. Comparing this equation to the given equation, we can see that Ea is replaced by the term ^-(^E_a), which is a constant at a given temperature. Thus, we can write ln k = ln A - (^-(^E_a)/R) * (1/T). Comparing this equation to the linear equation y = mx + b, we can see that the slope is -Ea/R, which is equivalent to choice C, -E_a/R.
