Question
For the reaction 2NO + Cl₂ → 2NOCl, the rate law is found to be rate = k[NO][Cl₂]. The overall order of the reaction is:
Correct Answer
Option C is the correct answer.
Detailed Explanation
The overall order is the sum of the exponents in the rate law. Here, exponent for NO is 1 and for Cl₂ is 1, so total order = 1+1 = 2.
Hint
Add the exponents of all reactant concentration terms in the rate law.
