With increase in temperature, the rate constant obeying Arhenious equation
A. Increases
B. Decreases
C. Decreases exponentially
D. Can either increase or decrease ; depends on the frequency factor
Answer: Option A
Solution (By Examveda Team)
According to the Arrhenius equation, the rate constant (k) increases with an increase in temperature.The Arrhenius equation is given by: $$k = A \exp \left( -\frac{E_a}{RT} \right)$$.
Here, k is the rate constant, A is the pre-exponential factor, Ea is the activation energy, R is the gas constant, and T is the temperature in Kelvin.
As the temperature T increases, the exponential term becomes larger, leading to an increase in the rate constant.
