Question

Consider the Arrhenius equation given below and mark the correct option.
`k=A e^(-(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.

Answer 1

Correct Answer - D
`k = Ae^(-E_(a)//RT)`
On increasing temperature and decreasing activation energy `E_(a)//RT` term overall decreases thus, `E_(a)//RT` term increases and rate constant increases exponentially,
