For a reaction , the rate law is found to be . If the concentration of is doubled and is halved, what happens to the rate?
- A.It remains unchanged
- B.It doubles
- C.It halves
- D.It quadruples
Show correct answer & step-by-step solution
Correct answer: A — It remains unchanged
Solution
- Initial rate .
- New concentrations are and .
- New rate .
- Since , the rate remains unchanged.
- Hence the answer is (A).
