<u>Answer:</u> The total pressure of container at equilibrium is 0.431 bar

<u>Explanation:</u>

We are given:

Pressure of hydrogen sulfide = 0.240 bar

The given chemical equation follows:

                      H_2S(g)\rightleftharpoons H_2(g)+S(g)

<u>Initial:</u>            0.240

<u>At eqllm:</u>      0.240-x        x      x

The expression of K_p for above equation follows:

K_p=\frac{p_{H_2}\times p_S}{p_{H_2S}}

We are given:

K_p=0.746

Putting values in above expression, we get:

0.746=\frac{x\times x}{0.240-x}\\\\x=0.191,-0.940

Neglecting the negative value of 'x' because pressure cannot be negative.

So, the equilibrium pressure of hydrogen gas = x = 0.191 bar

The equilibrium pressure of sulfur gas = x = 0.191 bar

The equilibrium pressure of hydrogen sulfide gas = (0.240 - x) = (0.240 - 0.191) = 0.049 bar

Total pressure of the container at equilibrium = p_{H_2}+p_{S}+p_{H_2S}

Total pressure of the container at equilibrium = 0.191 + 0.191 + 0.049 = 0.431 bar

Hence, the total pressure of container at equilibrium is 0.431 bar
