Options
- A2.5 10⁻⁶ ~mol dm ⁻³ sec ⁻¹
- B3.75 10⁻⁶ ~mol dm ⁻³ sec ⁻¹
- C5.0 10⁻⁶ ~mol dm ⁻³ sec ⁻¹
- D7.5 10⁻⁶ ~mol dm ⁻³ sec ⁻¹
Correct answer
D. 7.5 10⁻⁶ ~mol dm ⁻³ sec ⁻¹
Step-by-step solution
array ll & For the reaction, 2 NH _ 3( ~g ) Pt N _ 2( ~g ) +3 H _ 2( ~g ) & Rate of reaction =- 1 2 ~d [ NH ₃ ] dt = d [ N ₂ ] dt = 1 ~d [ H ₂ ] 3 & 2.5 10⁻⁶= 1 3 ~d [ H ₂ ] dt & d [ H ₂ ] dt =3 2.5 10⁻⁶=7.5 10⁻⁶ ~mol dm ⁻³ sec ⁻¹ array
