The dimerisation of `NO_2` as the temperature is lowered and accompanied by

When temperature is lowered NO_2 dimerises . It is accompanised by :

Why NO_2 dimerise to N_2O_4 ?

Dimerisation of NO_2, is an exothermic reaction. If enthalpy of reaction is /_\H, then the minimum value of activation energy for forward reaction (E_a) will be

What is the colour of NO_2 gas?

2NO_(2) iffN_(2)O_(4) . The dimerisation of NO_(2) is accompanied with :

Dimerisation of NO_2 , is an exothermic reaction. If enthalpy of reaction is /_\H , then the minimum value of activation energy for forward reaction (E_a) will be
