For the elementary processes whose equations are given below, determine whether each is unimolecular or bimolecular and determine the rate law for each process. Pick the choice which is correct.
a) NO(g) + Cl2(g) NOCl2(g) is bimolecular, with rate = k [NOCl2].
b) 2 Cl(g) Cl2(g) is unimolecular, with rate = k [Cl2].
c) NOCl2(g) NO(g) + Cl2(g) is unimolecular, with rate = k [NOCl2].
d) Cl2(g) 2 Cl(g) is unimolecular, with rate = k [Cl2]2.
e) Cl(g) + HBr(g) HCl(g) + Br(g) is bimolecular, with rate = k [HCl] [Br].
