Question

1) from k is the rate of the forward reaction initially greater than or less than that of the reverse reaction during the kinetic phase?
2)identify how a system will re- establish chemical equilibrium using LeChatliers principle ( with respect to changes in concentration) 1) from k is the rate of the forward reaction initially greater than or less than that of the reverse reaction during the kinetic phase?

Explanation / Answer

Q1.

If the process is considered spontaneous, then

K forward > K reverse

Since more products form than reactatnts

Q2.

Given an equilbirium constant, assume initially that:

- There is plenty of reactants

then, according to le Chatelier, the system most increas products concentration, decrease reactants until Q = Keq is achieved

If we add products / decrease reactatns, then we will favour the shift toward reverse reaction

Note that use of a catlyst will not change the equilibrium, only make it faster to achieve
