The number of given statement/s which is/are correct is

(A) The stronger the temperature dependence of the rate constant, the higher is the activation energy.

(B) If a reaction has zero activation

Question

The number of given statement/s which is/are correct is

(A) The stronger the temperature dependence of the rate constant, the higher is the activation energy.

(B) If a reaction has zero activation energy, its rate is independent of temperature.

(C) The stronger the temperature dependence of the rate constant, the smaller is the activation energy.

(D) If there is no correlation between the temperature and the rate constant then it means that the reaction has negative activation energy.

Analysis:

(A) TRUE — From Arrhenius equation: . Higher  means  changes more steeply with temperature (stronger temperature dependence). ✓

(B) TRUE — If :  = constant, independent of temperature. ✓

(C) FALSE — This is the opposite of (A). Higher  gives stronger temperature dependence. ✗

(D) FALSE — No correlation between  and  means , not negative. ✗

Number of correct statements = 2 (A and B)
