If K(equilibrium constant) is greater than Q(concentration constant at a prticular point) then the reaction will tend to the right. If Q is less that K the reverse reaction will occur and if they are...
A reversible reaction.
The reaction wants to shift to the side with fewer moles, so as to balance out with the increased pressure.
yes a decomposition reaction is a chemical reaction.
CO2 or carbon dioxide because a chemical reaction is when two or more elements bond together chemically in this case carbon and oxygen are bonding.
