8H2S(g)+4O2(g)→8H2O(g)+S8(g) Δ[H2S]/Δt = -0.012 M/s

a)Find Δ[O2]/Δt.

b)Find Δ[H2O]/Δt.

c)Find Δ[S8]/Δt.

d)Find the rate of the reaction.

Expert Solution

rate = decrease in concentration of reactant / time taken = increase in concentration of product / time taken.

a)

-1/8 [H2S] / t = -1/4 [O2] / t

[H2S] / t = - 0.012 M/s

[O2] / t = 4/8 [H2S] / t

[O2] / t = 4/8 (-0.012 )

[O2] / t = - 0.006 M/s

b)

-1/8 [H2S] / t = 1/8 [H2O]/t

- [H2S] / t = [H2O]/t

[H2O]/t = - (0.012)

[H2O]/t = 0.012 M/s

c)

1/8 [H2O]/t = [S8] / t

[S8] / t = 1/8 (0.012)

[S8] / t = 0.0015 M/s

d)

rate = [S8] / t

rate = 0.0015 M/s
