a,b,c.
Pressure. When pressure is steady.
d,e. color.
Cl2 is colored. Br2 is colored. When the intensity of the color is constant.
For each of these reactions, indicate the property which might be observed in order to determine when equilibrium has been reached.
a) PCl5(g) <--> PCl3(g) + Cl2(g)
b) CaCO3(s) <--> CaO(s) + CO2(g)
c) H2O(l) <--> H2O(g)
d) Cl2(g) + 2H2(g) H2(g) + 2HCl(g)
e) 2HBr(g) <--> H2(g) + Br2(g)
