Question

Write the rates for the following reactions in terms of the disappearance of reactants and appearance of products: (a) 302 ..... 203 (b) C2H6 ..... C2H4 + H2 (c) Clo- + Br- ..... Bro- + c1- (d) (CH3)3CCI + H20 ..... (CH3)3COH + tt+ + c1- (e) 2AsH3 ..... 2As + 3H2

Answer 1

Step-by-step explanation:

`\mathbf{From \ the \ information \ given:} \\ \\ \mathbf{The \ rates \ of \ the \ f ollowing \ reactions \ can \ be \ expressed \ as \ follows:}`

(a)

`\mathbf{3O_2 \to 2O_3} \\ \\ \\ \mathbf{-(1)/(3)(d[O_2])/(dt)=(2)/(3) (d[O_3])/(dt)}`

(b)

`\mathbf{C_2H_6 \to C_2H_4 + H_2} \\ \\ \\ \mathbf{ -(d[C_2H_6])/(dt)= (d[C_2H_4])/(dt)=(d[H_2])/(dt)}`

(c)

`\mathbf{ClO^-+Br^- \to BrO^-+Cl^-} \\ \\ \\ \mathbf{ -(d[ClO^-])/(dt)= -(d[Br^-])/(dt) = (d[BrO^-])/(dt) = (d[Cl^-])/(dt) }`

(d)

`\mathbf{(CH_3)_3 CCl+H_2O \to (CH_3)_3COH + H^+ + Cl^-} \\ \\ \\ \mathbf{- (d[(CH_3)_3CCl)/(dt)= - (d[H_2O])/(dt)= (d[CH_3)_3COH)/(dt)= (d[H^+])/(dt)= (d[Cl^-])/(dt)}`

(e)

`\mathbf{2AsH_3 \to 2As + 3H_2} \\ \\ \\ \mathbf{-(1)/(2)(d[AsH_3])/(dt)=(1)/(2)(d[As])/(dt)=(1)/(3)(d[H_2])/(dt)}`
