Consider the chemical reaction, N2(g) + 3H2(g) → 2NH3(g). The rate of this reaction can be expressed in terms of time derivative of concentration of N2(g), H2(g) or NH3(g). Identify the correct relationship amongst the rate expressions.
- Rate = –d[N2]/dt = – 1/3d[H2]/dt = 1/2d[NH3]/dt
- Rate = –d[N2]/dt = –3d[H2]/dt = 2d[NH3]/dt
- Rate = d[N2]/dt = –1/3d[H2]/dt = 1/2d[NH3]/dt
- Rate = d[N2]/dt = –d[H2]/dt = 1/2d[NH3]/dt
Answer
(A) Rate = – d [N 2 ]/ dt = – 1/3 d [H 2 ]/ dt = 1/2 d [NH 3 ]/ dt
