The rate constant, k of a zero order reaction 2 NH ₃( ~g ) 1130 ~K Pt N ₂( ~g )+3 H ₂( ~g ) is y 10⁻⁴ ~mol ~L ⁻¹ ~s ⁻¹ . The rate of formation of hydrogen (in mol L ⁻¹ ~s ⁻¹ ) is
Options
- Ay 10⁻⁴
- B2 y 10⁻⁴
- C3 y 10⁻⁴
- Dy 3 10⁻⁴
Correct answer
C. 3 y 10⁻⁴
Step-by-step solution
r = K [ NH ₃ ]^ = K = y 10⁻⁴ ~mol ~L ⁻¹ ~s ⁻¹ Now, aligned & 1 3 d [ H ₂ ] dt = r & d [ H ₂ ] dt =3 r =3 y 10⁻⁴ ~mol ~L ⁻¹ ~s ⁻¹ aligned
