If a reaction is endothermic does it favour reation or products?

Answer 1

if the reaction is an endothermic one, it means that it needs heat in order to occur, hence by heating you will get the products, and by cooling - the reactants.

Answer 2

In general, endothermic reactions would favor reactants. Endothermic reactions need energy to move forward.
Strictly speaking you should be thinking in terms of Gibbs free energy.
dG = dH - tdS, where d means change, and would be written as the Greek letter delta (which I cannot do in this text box).
When G is positive, reactants are favored.
When G is negative, products are favored.
G is positive when the reaction is endothermic (positive H) and entropy is decreasing (negative S).
G is negative when the reaction is exothermic (negative H) and the entropy is increasing (positive S).
If H and S have the same sign, then you must look at the actual values and the temperature. Generally speaking, if both are positive, the reaction can be made to favor the products by increasing the temperature to the point where TdS is greater than dH.
There are several concepts in this answer I did not explain. Ask about those if you are confused (and it looks like you are asking about other thermodynamics concepts). I would say thermodynamics is one of the hardest concepts to learn in chemistry. Best of luck!

Answer 3

you should read the chapter about thermodynamics again...


endotherm (H<0) means it absorbs heat, so its more likely to be non-spontaneous, but it depends on the entropy...

G=H+TS

only delta G can say wheter a reaction favours Educts or Products.

Answer 4

products.

Answer 5

possibly endo means outside so i would guess it sommit 2 do wit dat!!
