Text Solution
Verified by ExpertsC
The Arrhenius equation is given by 
.
Statement A: The factor 
represents the fraction of molecules having kinetic energy equal to or greater than the activation energy 
. Thus, statement A is incorrect.
Statement B: From the equation, as 
decreases, the value of 
increases, leading to a faster reaction rate. Thus, statement B is correct.
Statement C: For many reactions, the temperature coefficient is approximately 2, meaning the rate of reaction doubles for every 
rise in temperature. Thus, statement C is correct.
Statement D: Taking the natural logarithm of the Arrhenius equation, 
. Converting to base 10, 
. A plot of 
vs 
gives a straight line with slope 
. The statement says slope 
, which is only true for a 
vs 
plot. Thus, statement D is incorrect.
Therefore, statements B and C are correct.
