Rate of reaction for 2 X + Y 3 ~W + Z is 1.2 10⁻⁴ ~mol dm ⁻³ sec ⁻¹ when [ X ]=[ Y ]=0.6 ~mol dm ⁻³ Calculate value of rate constant if reaction is first order in X and zero order in Y
Options
- A1.2 10⁻⁴ ~mol dm ⁻³ sec ⁻¹
- B6 10⁻³ ~mol dm ⁻³ sec ⁻¹
- C2 10⁻⁴ ~mol dm ⁻³ sec ⁻¹
- D1.8 10⁻³ ~mol dm ⁻³ sec ⁻¹
Correct answer
C. 2 10⁻⁴ ~mol dm ⁻³ sec ⁻¹
Step-by-step solution
aligned & R =- 1 2 d [ X ] dt =- d [ Y ] dt = 1 3 d [ W ] dt = d [ Z ] dt & R = k [ X ] & 1.2 10⁻⁴= k (0.6) & k =2 10⁻⁴ ~mol dm ⁻³ sec ⁻¹ aligned
