Determine the rate equation, the rate constant, and the overall order for this reaction 


2NOCl(g) ⟶ 2NO(g) + Cl2 (g)


Step 1. Calculate the order

rate2rate1 = [NOCl]x of rate2[NOCl]x of rate18.0 × 10-103.2 × 10-9 = 0.20x[0.10]x4 = [2]x

2 raised to 2 = 4

x = 2 → 2nd order

Since there is only 1 reactant, the overall order is 2nd order


Step 2. Setup rate law

The rate law of the reaction is: rate =k[NOCl]2
