The units of the rate constant for a second order reaction are__________________?
Correct answer: C. Moles-1. sec1
- A. Sec-1. mole°
- B. Moles1. sec-1
- C. Moles-1. sec1
- D. Moles1. sec1
Explanation
For a second-order rate law, rate = kC², so k = rate/C². Its units are concentration⁻¹ time⁻¹, commonly L mol⁻¹ s⁻¹, matching option c despite the compressed superscript formatting.
