Hydrogen sulfide decomposes according to the following reaction, for which Kc = 9.30 10-8 at 700°C. 2 H2S(g) 2 H2(g) + S2(g) If
Vikentia [17]

Answer:

The equilibrium concentration of hydrogen gas is 0.0010 M.

Explanation:

The equilibrium constant of the reaction = K_c=9.30\times 10^{-8}

Moles of hydrogen sulfide = 0.31 mol

Volume of the container = 4.1 L

[concentration]=\frac{moles}{volume (L)}

[H_2S]=\frac{0.31 mol}{4.1 L}=0.076 M

2H_2S(g)\rightleftharpoons 2H_2(g)+S_2(g)

Initially

0.076 M

At equilibrium

(0.076-2x)                         2x     x

The expression of an equilibrium constant :

K_c=\frac{[H_2]^2[S_2]}{[H_2S]^2}

9.30\times 10^{-8}=\frac{(2x)^2\times x}{(0.076-x)^2}

Solving for x:

x = 0.00051

The equilibrium concentration of hydrogen gas:

[H_2]=2x=2\times 0.00051 M=0.0010 M

Which factors can influence the length of time it takes for a half-life to occur?
vovikov84 [41]

Answer:

the radioactive half-life of an atom can depend on how it is bonded to other atoms. by changing the neighboring atoms that are bonded to a radioactive isotope, we can change its half-life.

In chemistry, some changes are reversible and some are irreversible, explain.
Aliun [14]
The denaturing of proteins is irreversible. For example, eggs cannot be unboiled. Other reactions, such as the formation of carbonic acid, are reversible.
