Question

How will an increase in temperature affect each of the following equilibria? How will a decrease in the volume of the reaction vessel affect each?                      (a) 2NH3(g)   ⇌     N2(g)+3H2(g)      ΔH = 92kJ

                     (b) N2(g)   +    O2(g)   ⇌    2NO(g)         ΔH =181kJ

                     (c) 2O3(g)   ⇌    3O2(g)                    ΔH = − 285kJ

                     (d) CaO(s)  +   CO2(g)   ⇌  CaCO3(s)      ΔH = − 176kJ
