Consider the reaction for the decomposition of hydrogen disulfide:

2H2S(g)⇌2H2(g)+S2(g),2H2S(g)⇌2H2(g)+S2(g),  
KcKc = 1.67×10−71.67×10−7 at 800∘C∘C

The reaction is carried out at the same temperature with the following initial concentrations:

[H2S][H2][S2]===4.70×10−4M0.00M0.00M[H2S]=4.70×10−4M[H2]=0.00M[S2]=0.00M

Part A

Find the equilibrium concentration of S2S2.

Express the concentration to three significant figures and include the appropriate units.

[S2][S2] = nothingnothing
