Question

The decomposition of gaseous dinitrogen oxide in the presence of Cl2 at high temperatures is thought to follow the mechanism, Cl2(g) + 2 CI (9) N2O(g) + Cl (g) – N2(g) + CIO(g) 2 CIO(g) - C12(g) + O2(g) In the net overall reaction, the second step occurs twice for each occurrence of the first and third steps. In this mechanism, the catalysts are , and the intermediates are O A. catalysts - Cl2 & Cl; intermediates - CIO O B. catalysts - Cl2 ; intermediates - CI O C. none of these OD. catalysts - Cl2: intermediates CI & CIO O E. catalysts - CI & CIO ; intermediates - Cl2

Answer 1

Chcgl ?(169) N2O(g) & clcgl Nalg) + (1019) 2010 (9) - Clz (91 + 0219) Overall reaction is obtained as Claig 2011g! + 2N2019) + 2011g) - 2N214) + 261019) + 2010 (9) C121g) + O2lg 1 2N20 (9) 2N2 1g) + Osig) net overall reaction A catalyst enters in step 1. and regenerated in last It is not consumed in reaction. while a intermediate is formed in one step during mechanism and consumed in another step. Intermediate cannot be regenerstedt from Mechanism (cle is catalyst cond(s) and C10) 45e intermediate) = C12 - catalyst (1 and cio are intermediates. Hence, option is correct..
