Vedclass · Answer

(A) For a general reaction $aA + bB ightarrow cC + dD$,the average rate is given by: $	ext{Rate} = -\frac{1}{a} \frac{\Delta[A]}{\Delta t} = -\frac{1}{b} \frac{\Delta[B]}{\Delta t} = \frac{1}{c} \frac{\Delta[C]}{\Delta t} = \frac{1}{d} \frac{\Delta[D]}{\Delta t}$.For the reaction $N_{2(g)} + 3H_{2(g)} ightarrow 2NH_{3(g)}$,the stoichiometric coefficients are $1$,$3$,and $2$ respectively.Thus,the rate expression is: $-\frac{\Delta[N_2]}{\Delta t} = -\frac{1}{3} \frac{\Delta[H_2]}{\Delta t} = \frac{1}{2} \frac{\Delta[NH_3]}{\Delta t}$.
