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

question 36

Multiple Choice

Nitric oxide reacts with chlorine to form nitrosyl chloride, NOCl. Use the following data to determine the rate equation for the reaction.NO + ¹/₂Cl₂ $\rarr$ NOCl $\begin{array}{llll}\text { Expt. \# } & [\mathrm{NO}] & {\left[\mathrm{Cl}_{2}\right]} & {\text { Initial Rate }} \\\hline 1 & 0.22 & 0.065 & 0.96 \mathrm{M} / \mathrm{min} \\2 & 0.66 & 0.065 & 8.6 \mathrm{M} / \mathrm{min} \\3 & 0.44 & 0.032 & 1.9 \mathrm{M} / \mathrm{min}\end{array}$

• 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
