If experimentally observed rate constant is greater than the maximum value of rate constant obtained using hard-sphere model of collision theory, then relation between the impact parameter (b) and sum of the radii of two reactants is
(b)$\mathrm{b}<\mathrm{r}_{1}+\mathrm{r}_{2}$
(a)$b=r_{1}+r_{2}$
(c)$b>r_{1}+r_{2}$
(d)$b \leq r_{1}+r_{2}$
