Rate of a reaction can be expressed by Arrhenius equation as:
$$$k = A\,{e^{ - E/RT}}$$$ In this equation, E represents

the energy above which all the colliding molecules will react

the energy below which colliding molecules will not react

the total energy of the reacting molecules at a temperature, T

the fraction of molecules with energy greater than the activation energy of the reaction

The following mechanism has been proposed for the reaction of NO with Br₂ to form NOBr:
NO(g) + Br₂ (g) $$\leftrightharpoons$$ NOBr₂ (g)
NOBr₂ (g) + NO (g) $$\to$$ 2NOBr (g)
If the second step is the rate determining step, the order of the reaction with respect to NO(g) is
