Given below are two statements is one labelled as Assertion A and the other is labelled as
Reason R.
Assertion
A
A reaction can have zero activation energy.
Reason (R) The minimum extra amount of energy absorbed by reactant molecules so that their energy becomes equal to threshold value, is called activation energy. choose the correct answer from the options given below.
Both A and R are true and R is the correct explanation of
.
Reason (R) The minimum extra amount of energy absorbed by reactant molecules so that their energy becomes equal to threshold value, is called activation energy. choose the correct answer from the options given below.
Both A and R are true and R is the correct explanation of
. B
Both A and R are true but R is not the correct explanation of A .
C
is true but 
is false. D
is false but 
is true.
Text Solution
Verified by ExpertsThe correct answer is:
C
A is false but R is true. When a reaction have zero activation energy, the initial energy of the
reactant will be equal to the activation energy of the reaction. That means every collision results into a chemical reaction which is not possible. Mathematically,
If 
, then according to Arrhenius equation.
