Equalibrium & Le chatliers principle

[faisal]

When your increase the concentration do you increase the yield of products?
And if you increase temperature will the system oppose this change and reduce the temperature applying le-chitaliers principle, and how much yield would you get if temperature is increased/reduced?

[Artermis]

Given
A + B <==> C + D at equilibrium
If you increase the concentration of A, there will be a shift in equilibrium towards the right side of the equation and a decrease in concentration of B.
For the temperature it depends on whether or not the reaction is an exothermic reaction or an endothermic reaction. I'll let you think about this one...
Endothermic reaction:
heat + A + B <==> C + D
Exothermic reaction:
A + B <==> C + D + heat
