1.	Consider the chemial reaction N_2(g) + 3H_2(g)to 2NH_3(g). The rate of this reaction can be expressed in term of time derivatives of concentration of N_2(g), H_2(g) or NH_3(g). Identify the correct realtionship amongst the rate expressions:
Answer» Rate `= -(d[N_2])/(DT) = 1/3(d[N_2])/(dt) = 1/2(d[NH_3])/(dt)` Rate `= (d[N_2])/(dt) = -3(d[H_2])/(dt) = 2(d[NH_3])/(dt)` Rate `=(d[N_2])/(dt) = 1/3(d[N_2])/(dt) = 1/2(d[NH_3])/(dt)` Rate `=(d[N_2])/(dt) = -(d[H_2])/(dt) = (d[NH_3])/(dt)` Solution :For chemical reaction `N_2(g)+ 3H_2(g) to 2NH_2(g) ` The rate of reaction is EXPRESSED as FOLLOWING Rate `=-(d[N_2])/(dt) = -1/3(d[H_2])/(dt) = + 1/2(d[NH_2])/(dt)` In the progress of reactionsd, concentration of `N_2` and `H_2` are decreased, so negative sign is REPRESENTED in expression, while concentration of `NH_2` are decreased, so negative sign is represented in expression, while concentration of `NH_3` is increased, so POSITIVE sign is represented inexpression
