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
