Vedclass · Answer

(B) The rate of reaction for $N_2 + 3H_2 	o 2NH_3$ is given by: $-\frac{\Delta [N_2]}{\Delta t} = -\frac{1}{3} \frac{\Delta [H_2]}{\Delta t} = \frac{1}{2} \frac{\Delta [NH_3]}{\Delta t}$ From the relation $-\frac{1}{3} \frac{\Delta [H_2]}{\Delta t} = \frac{1}{2} \frac{\Delta [NH_3]}{\Delta t}$,we get: $-\frac{\Delta [H_2]}{\Delta t} = \frac{3}{2} 	imes \frac{\Delta [NH_3]}{\Delta t}$ Substituting the given value $\frac{\Delta [NH_3]}{\Delta t} = 2 	imes 10^{-4} \ mol \ L^{-1} s^{-1}$: $-\frac{\Delta [H_2]}{\Delta t} = \frac{3}{2} 	imes 2 	imes 10^{-4} \ mol \ L^{-1} s^{-1} = 3 	imes 10^{-4} \ mol \ L^{-1} s^{-1}$

$t / s$	$0$	$30$	$60$	$90$
$[A] / mol \ L^{-1}$	$0.55$	$0.31$	$0.17$	$0.085$

For the reaction $N_2 + 3H_2 \to 2NH_3$,if $\frac{\Delta [NH_3]}{\Delta t} = 2 \times 10^{-4} \ mol \ L^{-1} s^{-1}$,the value of $\frac{-\Delta [H_2]}{\Delta t}$ would be
