Why `NO_2` shows tendency to form `N_2O_4`?

Why does NO_2 dimerise to form N_2O_4 ?

Why Boron family has a tendency to form hydrides?

Why He_2 is not formed?

In a reversible chemical reaction, 2NO_2 overset(k_1) underset(k_2) iff N_2O_4 the rate of disappearance of NO_2 is equal to

This question has Statement I and Statement II. Of the four choices given after the Statements, choose the one that best describes the two Statements Statement - I: For the equilibrium N_2O_4(g) iff 2 NO_2(g) , if volume of the vessel is reduced to half of its original volume, equilibrium constant will be doubled. Statement - II , Decrease of volume to half doubles the concentration of N_2O_4 as well as NO_2

Why do transition elements have a greater tendency to form co-ordinate compounds?

The standard Gibbs free energy (/_\G^(@)) at 25^(@) C for the dissociations of N_2O_4 (g) to NO_2 (g) is (given : equilibrium constant =0.15,R=8.314J*K^(-1)mol^(-1)
