Consider the following reaction: 2H2S(g)+SO2(g)⇌3S(s)+2H2O(g) A reaction mixture initially containing 0.500 M H2S and 0.500 M SO2 was found to contain 1.3×10−3 M H2O at a certain temperature. A second reaction mixture at the same temperature initially contains [H2S]= 0.255 M and [SO2]= 0.325 M . Calculate the equilibrium concentration of H2O in the second mixture at this temperature.
