Answer:
The equilibrium law
Explanation:
According to the equilibrium law , when
of any of the reactants or the products in the reaction at an equilibrium state, is changed, then it changes the composition of equilibrium mixture in order to minimize the effect of
Acetic acid (in excess) +
⇄
+ water
is a reaction which involves the equilibrium. So to force the reaction towards the side of
, one of the reactant is taken in excess. All this can be explained easily by applying the equilibrium law.
False. It can’t because a glaciers weight combined with its gradual movement can drastically reshape the landscape over hundreds and even thousands of years.
Answer:
Explanation:
Entropy is the degree of randomness or disorderliness of as system. The more random a system tends, the more positive the entropy. Gases have the highest entropy whereas solids have little to no entropy.
When a reaction goes from one initally with a lower entropy to one with a higher entropy, the change in entropy, ΔS is postive. ΔS is negative when a reaction goes from one with a higher entropy to one with lower entropy.
When there is no entropy change, both the reactants and products are in the same state.
In the first reaction, UF₆ is in a gaseous phase and it was seperated into two gaseous products, 238-UF₆ and 235-UF₆. Therefore, ΔS is zero i.e no change in entropy of the system.
In the second reaction, solid I₂ is dissolved in CCl₄. The solid substance goes into solution to form a liquid medium. This is an increase in the randomness or entropy of the system. Therefore ΔS is +ve.
Starch Im pretty sure correct me if Im wrong Hope I helped
