anyways.. your question.
increasing the pressure will shift the equilibrium to the side with less molecules
so for example A+B <-> C , increasing the pressure here will shift the equilibrium to the right & youll get a higher yield
decreasing the pressure will shift equilibrium to the side with more molecules
*only applies to gases
increasing the temperature will favour the forward reaction in an endothermic reaction
decreasing the temperature will favour the forward reaction in an exothermic reaction
increasing the concentration on the reactants side will shift equilibrium to the right & hence increasing yield
increased concentration on the products side will shift equilibrium to the left & hence the rate of backward reaction will be greater than the forward reaction.
hope it helps? :b lol.
