Question

Which type of graph plot is used to analyze the effect of temperature on the rates of chemical reactions?

(a) Dot plot

(b) Normal probability plot

(c) Arrhenius plot

(d) Line weaver-Burk plot

I got this question during an interview for a job.

My doubt is from Data Analysis topic in portion Presentation and Analysis of Data of Bioprocess Engineering

Answer 1

Correct option is (c) Arrhenius plot

Explanation: An Arrhenius plot displays the logarithm of kinetic constants (ln (k), ordinate axis) plotted against inverse temperature (1/T, abscissa). The Arrhenius equation can be written as:

ln (k) = ln (A) – (Ea/R) (1/T)

Where :

k = Rate constant

A = Pre-exponential factor

Ea = Activation energy

R = Gas constant

T = Absolute temperature, K

In the right, which represents the y-coordinate axis.
