Question

What is the slope of the plot of ln (t0.5) and ln (CAo)? (Where n is the reaction order)

(a) 1-n

(b) 2-n

(c) n

(d) \(\frac{n}{2} \)

I have been asked this question during an interview.

My question is from Rate Data Collection & Analysis in division Collection and Analysis of Rate Data of Chemical Reaction Engineering

Answer 1

The correct option is (a) 1-n

The explanation is: The plot is a straight line of slope (1-n). The equation representing the relationship is ln (t0.5) = ln\((\frac{(2^{n-1}-1)}{(n-1)k})\) + (1 – n) ln (CAo).
