The following mechanism was proposed for the formation of COCl 2 from CO and Cl 2. Step 1 Cl 2 (g) = 2 Cl (g) (fast) Step 2 CO (g) + Cl (g) - COC () (slow) Step 3 COCI(g) + Cl(g) → COCI 2 (E) (fast) Write the rate law expression. O rate = k[CO][C12]1/2 rate = k[Cl2]1/2 rate = k [COCI][CI] rate= k[CO][CI] rate= K[CO](C12] Which of the following changes, at equilibrium, would increase the yield of SiCl...
