What are the driving forces behind an endothermic rxn?

Answer 1

No endothermic reaction can be successful without an increase in entropy. This can be thought of as the disorder of a system, and in this context usually means that endothermic reactions can only be successful if lots of moles of gas are on the product side of the equation, or if a solid dissolves to make a solution.

Answer 2

the driving forces of any reaction will be decrease in free energy and the increase in the entropy.entropy is the the extent of disorder in a molecule. according to the theory,every substance wants to be free from bondages[ same as we people]and wants to be free or in another sense they are longing for disorder.gaseous phase has the maximum disorder because of the ability of molecules for the random motion.2nd place for liquids and unfortunately the last place for solids as the molecules are tightly packed and there's limited scope for movement.
ther's an equation for finding out the free energy called gibbs-helmoltz equation:
delta G=delta H-Tdelta S
where delta symbolizes change in the parameter like[free energy[G] or enthalpy[H] or entropy[S]]
change means difference, that is initial - final
for an endothermic reaction ,in sign convention delta H is -ve as initial H is higher than final and T is the absolute temperature which cannot be -ve. for the endothermic reactions spontaneous at the temperature T. delta G should be negetive.[the most important condition]
this is driving force for an endothermic reactions.

Answer 3

an endothermic rxn is that in which the bonds that are being broken require a lot of energy cuz they are very stable than the bonds that are going to be formed . it has a high activation energy and the delta H is positive if yuo want to know all the forces go to Phd level and find out.(very complex, been there done that)

Answer 4

Well there is no driving force, the reaction itself will not happen on its own. It is nonspontaneous. The only way for this reaction to occur is if heat energy is supplied. This will force the reaction to move forward and produce products.

Answer 5

either you increase enthalpy in the reactants or the product has an increase in entropy

(delta)G=(delta)H-T(delta)S

(delta) = change in
G= free energy(if negative then spontanious)
H=enthalpy
T=temperature
S=entropy
