The chlorine-atom-catalyzed chlorination of methane is thought toproceed by a two-step mechanism:
CH4(g) + Cl(g) --> CH3(g) + HCl(g) (slow)
CH3(g) + Cl2(g) --> CH3Cl(g) + Cl(g)
1) If the first step of this mechanism is rate-determining (slow),choose the correct rate law for the overall process.
A) Rate = k [CH4] [Cl2]
B) Rate = k [CH3] [Cl2]
C) Rate = k [CH4]2
D) Rate = k [CH4]2 [Cl2]
E) Rate = k [Cl] [CH4]
F) Rate = k [Cl] [CH3]
2) Choose the correct chemical equation for the overallprocess.
A) CH4(g) + Cl2(g) --> CH3Cl(g) + HCl(g)
B) CH4(g) + Cl(g) --> CH3(g) + HCl(g)
C) CH3(g) + Cl2(g) --> CH3Cl(g) + Cl(g)
3) Identify an intermediate in the reaction.
A) CH4
B) CH3
C) Cl
D) CH3Cl
I think number one is B but I'm not sure.
