(A) The rate of reaction is given by the expression: $-\frac{d[N_2]}{dt} = -\frac{1}{3} \frac{d[H_2]}{dt} = \frac{1}{2} \frac{d[NH_3]}{dt}$.Given that the rate of disappearance of $N_2$ is $-\frac{d[N_2]}{dt} = 2.22 \times 10^{-3} \ mol \ dm^{-3} \ s^{-1}$.From the stoichiometric relationship,we have: $\frac{d[NH_3]}{dt} = 2 \times (-\frac{d[N_2]}{dt})$.Substituting the given value: $\frac{d[NH_3]}{dt} = 2 \times (2.22 \times 10^{-3} \ mol \ dm^{-3} \ s^{-1}) = 4.44 \times 10^{-3} \ mol \ dm^{-3} \ s^{-1}$.
