JEE Main · ChemistryEasy
For a reaction , the rate of reaction doubles when the concentration of is doubled. What is the order of the reaction?
- A.Zero order
- B.First order
- C.Second order
- D.Third order
Show correct answer & step-by-step solution
Correct answer: B — First order
Solution
- The rate law is given by .
- When concentration is doubled, the new rate is .
- Dividing the two equations gives .
- Solving for gives .
- Hence the answer is (B).
