For a reaction, 2 ~A + B 2 C , rate of disappearance of A is 0.076 ~mol dm ⁻³ ~s ⁻¹ . What is the rate of disappearance of B ?
Options
- A0.152 ~mol dm ⁻³ ~s ⁻¹
- B0.114 ~mol dm ⁻³ ~s ⁻¹
- C0.038 ~mol dm ⁻³ ~s ⁻¹
- D0.076 ~mol dm ⁻³ ~s ⁻¹
Correct answer
C. 0.038 ~mol dm ⁻³ ~s ⁻¹
Step-by-step solution
aligned & - 1 2 d [ A ] d t =- d [ B ] d t & - d [ B ] d t = 1 2 0.076 & =0.038 ~mol dm ⁻³ ~s ⁻¹ aligned
