According to the Arrhenius equation (k = A * e^(-Ea / RT)), what graph yields a straight line whose slope equals -Ea / R?
Answer and explanation
Correct answer: C. ln k versus 1 / T
Taking the natural log: ln k = ln A - (Ea / R)*(1 / T). Plotting y = ln k versus x = 1/T yields a linear graph with slope = -Ea / R and y-intercept = ln A.
