The rate constant k , for the reaction N ₂ O _ 5( ~g ) 2 NO _ 2( ~g ) +1 / 2 O _ 2( ~g ) is 2.3 10⁻² ~s ⁻¹ . Which equation given below describes the change of [ N ₂ O ₅ ] with time? [ N ₂ O ₅ ]₀ and [ N ₂ O ₅ ]_t correspond to concentration of N ₂ O ₅ initially and at time t .
Options
- A[ N ₂ O ₅ ]_t= [ N ₂ O ₅ ]₀+k t
- B[ N ₂ O ₅ ]_t= [ N ₂ O ₅ ]₀ e^ k t
- C[ N ₂ O ₅ ]_t= [ N ₂ O ₅ ]₀+k t
- D[ N ₂ O ₅ ]₀ [ ~N ₂ O ₅ ]_t =k t
Correct answer
D. [ N ₂ O ₅ ]₀ [ ~N ₂ O ₅ ]_t =k t
Step-by-step solution
aligned & k= 1 t a( initial ) a-x( after time t) & k t= [ N ₂ O ₅ ]₀ [ ~N ₂ O ₅ ]_t aligned
