Consider the reaction described by the following equation. CO2(g)+H2(g)⇌CO(g)+H2O(g) How will the position of the equilibrium change if the volume of a vessel that contains this reaction is decreased?

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.
