1) In the Arrhenius plot slope is -(Ea/R). Where Ea is the activation energy. Negative slope signifies that activation energy is positive.
2)Generaly the slope is negative,but for some special reaction (catalytic reaction & formation of NO2) slope becomes positive,when the rate of mass loss decreases with respect to the increase in temperature.
3) Non Arrhenius behaviour is seen in catalytic reactions, explosion reactions & in formation reaction of NO2
2NO + O2 = 2NO2
