$A + H_2O + CO_2 \to B$
$B + NaCl \to C + NH_4Cl$
$C\xrightarrow{\Delta }D + {H_2}O + C{O_2}$
Incorrect statement is
$Cl_2(aq)+H_2SO_4(aq) \rightarrow S(s)+2H^+(aq)+2Cl^-$
The rate equation for this reaction is
rate $=k[Cl_2][H_2S]$
Which of these mechanisms is/are consistent with this rate equation ?
$A.\,\, Cl_2 + H_2S \rightarrow H^+ + Cl^- + Cl^+ + HS^-\,\, (slow)$
$Cl^+ +HS^- \rightarrow H^+ +Cl^- +S \,(fast)$
$B.\,\, H_2S \rightleftharpoons H^+ + HS^-\,$ (fast equilibrium)
$Cl_2^+ + HS^- \rightarrow 2CI^- + H^+ + S\,\, (Slow)$
