Decrease in volume will have no effect on equilibrium in the following system:
5) H2 (g) + CO2 (g) <-----> CO (g) + H2O (g)
As the volume is decreased, the pressure increases. That is the partial pressure of gaseous rectants and products increases. So according to Le Chatelier's principle, the reaction will shift towards fewer gaseous compounds side. But here there are equal number of gaseous compounds on reactants and products side. So decrese in volume will not effect the equilibrium.
