Pressure in Reversible reactions

Can someone explain to me how pressure affects a reversible reaction and how the reaction shifts to go back to equilibrium

Can someone explain to me how pressure affects a reversible reaction and how the reaction shifts to go back to equilibrium i assume by reversible you mean a reaction in equilibrium. pressure happens when gas molecules collide, the fewer molecules the less pressure, the more molecules the more pressure. it is evident you know equilibrium reactions do not complete, but when they are faced with a change, they act in a way that opposes the change. in this case, when pressure is increased, it will go shift towards the side with the least number of gaseous molecules, and when decreased will shift towards the side with the most gaseous molecules.
