A) The energy above which not all the colliding molecules will react
B) The energy below which colliding molecules will not react
C) The total energy of the reacting molecules at temperature T
D) The fraction of molecules with energy greater than the activation energy of the reaction
Correct Answer: B
Solution :
Variation of rate constant, k with temperature T (K) is given by Arrhenius equation. \[k=A{{e}^{-{{E}_{a}}/RT}}\]where\[{{E}_{a}}=\] activation energy, (the energy below which colliding molecules will not react) A = frequency factor.
