2 H2(g) + S2(g) equilibrium reaction arrow 2 H2S(g) At a certain temperature, Kc = 1.30 ✕ 1010 for the reaction above. Calculate the equilibrium concentration of H2S if [H2] = 0.00400 M and [S2] = 0.00270 M at equilibrium in a container.

The equilibrium concentration of hydrogen sulfide is 23.7 M

Explanation:

For the given chemical equation:

The expression of for above equation follows:

We are given:

Putting values in above expression, we get:

Neglecting the negative value of 'x' because concentration cannot be negative

Hence, the equilibrium concentration of hydrogen sulfide is 23.7 M
