<span>Each mole contains Avagodro's number of atoms i.e. 6.023x10^23, so
3 moles x 6.023x10^23 atoms/mole = 18.069x10^23 atoms = 1.8x19^24 atoms </span>
Following reaction is involved in above system HOCl(aq) ↔ H+(aq) + OCl-<span>(aq) </span>OCl-(aq) + H2O(l) ↔ HOCl(aq) + OH-<span>(aq) </span> Now, if the system is obeys 1st order kinetics we have K = [OCl-][H+<span>]/[HOCl] ............. (1) </span>∴ [HOCl-] / [OCl-] = [H+] (1 / 3.0 * 10-8<span>) ............. (2) </span> and now considering that system is obeying 2nd order kinetics, we have K = [OH-][HOCl-] / [OCl-] ................. (3<span>) </span>Subs 2 in 3 we get K = [OH-][H+] (1 / 3.0 * 10-8<span>) </span>we know that, [OH-][H+] = 10<span>-14
</span>∴K = 3.3 * 10<span>-7 </span> Thus, correct answer is e i.e none of these
