Determine if the following mechanism is valid.

Step 1: NOCl (g) ⇌ NO (g) + Cl (g)         (fast)

Step 2: NOCl (g) + Cl (g) → NO (g) + Cl₂ (g)          (slow)

Consider the rate law. rate=𝑘[a]^𝑥 determine the value of 𝑥 if the rate doubles when [a] is doubled.

Consider the rate law. Rate = k[A]^x. Determine the value of x if the rate doubles when [A] is doubled.
