1.	Rate of a reaction can be expressed by Arrhenius equation as: `k = Ae^(-E_(a)//RT)` In this equation, `E_(a)` represents:A. (a) The energy above which all the colliding molecules will reactB. (b) The energy below which colliding molecules will not reactC. (c ) The total energy of the reactant molecules at a temperature `T`D. (d) the fraction of molecules with enrgy greater than the activation energy of the reaction`
Answer» Correct Answer - b `E` is activation energy. Thus order with respect to NO is `2`. If `E_(a)+E_(R)=E_("Threshold enrgy")`, then only molecule may react.
