For the reaction: 2NO(g)+Cl₂( g)→2NOCl(g) the real rate law is rate =k[NO] [Cl₂].
If the following steps are the mechanism, which one must be the rate determining step? NO(g)+Cl₂( g)→NOCl₂( g) step one
NO(g)+NOCl₂( g)→2NOCl(g) step two
O step one
O step two
O not enough information given to determine
O both must be slow
