During the decomposition of H ₂ O ₂ to give oxygen, 48 ~g O ₂ is formed per minute at a certain point of time. The rate of formation of water at this point is
Options
- A0.75 ~mol ~min ⁻¹
- B1.5 ~mol ~min ⁻¹
- C2.25 ~mol ~min ⁻¹
- D3.0 ~mol ~min ⁻¹
Correct answer
D. 3.0 ~mol ~min ⁻¹
Step-by-step solution
2 H ₂ O ₂ 2 H ₂ O + O ₂ Rate =- 1 2 d [ H ₂ O ₂ ] d t = 1 2 d [ H ₂ O ] d t = d [ O ₂ ] d t Rate of formation of oxygen =48 ~g ~min ⁻¹ aligned & = 48 32 ~mol ~min ⁻¹=1.5 ~mol ~min ⁻¹ & Rate of formation of H ₂ O & 1 2 d [ H ₂ O ] d t = d [ O ₂ ] d t & d [ H ₂ O ] d t =2 d [ O ₂ ] d t =2 1.5=3 ~mol ~min aligned
