Nitric Oxide Reacts with Chlorine to Form Nitrosyl Chloride, NOCl $\rarr$

Nitric oxide reacts with chlorine to form nitrosyl chloride, NOCl.Use the following data to determine the rate equation for the reaction.
NO + ¹/₂Cl_{2S1U1 $\rarr$ NOCl}

A) rate = k[NO]
B) rate = k[NO][Cl₂]^1/2
C) rate = k[NO][Cl₂]
D) rate = k[NO]²[Cl₂]
E) rate = k[NO]²[Cl₂]²
