STANDARD Chemistry Arrhenius Equation MCQ Question

Type: MCQ-conceptual-Medium-Class 12

Consider the Arrhenius equation given below and mark the correct option. k = Ae⁻ᴱₐ/ᴿᵀ

A

Rate constant increases exponentially with increasing activation energy and decreasing temperature.

B

Rate constant decreases exponentially with increasing activation energy and decreasing temperature.

C

Rate constant increases exponentially with decreasing activation energy and decreasing temperature.

D

Rate constant increases exponentially with decreasing activation energy and increasing temperature.

Correct Answer

Option D

Detailed Explanation

On increasing temperature and decreasing activation energy, Eₐ/RT term overall decreases thus, –Eₐ/RT term increases and rate constant increases exponentially.
