Consider a mixture of N₂ (1) and H(2) molecules. If the number of collisions

per unit time per unit volume between N₂ and H₂ is equal to the number of collisions

per unit time per unit volume between N₂ and N₂ molecules , calculate the ratio of

number densities _{1 / 2} at given temperature T. d_N2 = 0.373 x 10^-9m and

d_H2 = 0.271 x 10^-9m . N:14, H:1 Avagadro number 6.02x 10²³.
