Problem
When the two reactions below occur simultaneously at 500 K,
(1) X2(g)⇌2X(g)Q1=4.0
(2) 2X(g)+Y2(g)⇌2XY(g)Q2=0.25
write the overall reaction, calculate Qoverall, and state whether the mixture will shift toward products, toward reactants, or remain unchanged if Koverall=1.2 at the same temperature.
