Question

Match the following reactions in Column I with their unit of rate constant in Column II: Column I: (A) $SO_2$$Cl_2$ -> $SO_2$ + $Cl_2$ (B) CH3COOC2H5 + $NaOH$ -> CH3COONa + $C_2H_5OH$ (C) 2$H_2O_2$ -> 2$H_2O$ + $O_2$ (D) $H_2O_2$ + 2I^- + 2H^+ -> 2$H_2O$ + $I_2$ Column II: (P) s^-1 (Q) min^-1 (R) L mol^-1 min^-1 (S) L mol^-1 s^-1
