Question

Which of the following is in accordance with the Arrhenius equation?
a) Rate of a reaction increases with decrease in activation energy
b) Rate constant decreases exponentially with increase in temperature
c) Rate of a reaction increases with increase in temperature
d) Rate of reaction does not change with increase in activation energy

Answer 1

Dear Student,

$Arrheniusequationisk=A.e^{-\frac{E_a}{RT}}$
The increase in temperature increases the exponential value which ultimately increases rate of reaction and similarly the increase in activation energy decreases the value of exponential results in decreased rate of reaction. Hence the answer is Option (A) and (C)
