Question

Consider the Arrhenius equation given below and mark the correct option.
$k = Ae^{-\frac{E_a}{RT} }$
(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

Answer:Option (d)

Explanation:With increase in the value of Ea, the value of k will decrease as the power of e is negative Ea/RT.
