Select all that apply.

The rate law for the reaction

2NO(g) + Cl2(g)

→

2NOCl(g)

is given by R = k[NO][Cl2]

If the following is the mechanism for the reaction,

NO(g) + Cl2(g)

→

NOCl2(g)

NOCl2(g) + NO(g)

→

2NOCl(g)

which of the following statements accurately describes this reaction? Check all that apply.
  

2nd order reaction
  

The first step is the slow step.
  

Doubling [NO] would quadruple the rate.
  

Cutting [Cl2] in half would decrease the rate by a factor of two.
  

The molecularity of the first step is 1.
  

Both steps are termolecular.
