Question

1.   (a)    The following Table 1 shows kinetic study values obtained from second order the gas phase reaction.

                                        X₂ + H₂   → 2HX

Table 1

T (K) k (cm³ mol^-1 s^-1)

600 4.6 x 10²

700 9.7 x 10³

800 1.3 x 10⁵

1000 3.1 x 10⁶ 

[Average molar mass of reactant is 128 g mol^-1]                  

Find:

(i)           The collision frequency at 700 K (in m³ s^-1).

(ii)          The collisions diameter.
