STANDARD Chemistry Arrhenius Equation MCQ Question
The temperature dependence of the rate constant k is expressed as k = Ae⁻ᴱᵃ/ᴿᵀ. When a plot between log k and 1/T is plotted, we get the graph as shown. What is the value of slope in the graph?
Eₐ/RT
-Eₐ/2.303R
-Eₐ/2.303RT log A
-EₐR/2.303T
Correct Answer
Detailed Explanation
The slope of the Arrhenius plot (log k vs 1/T) is -Eₐ/2.303R, where Eₐ is the activation energy and R is the gas constant.
