Explanation:
Let us proceed with a reaction
A(aq)+B(aq) C(aq) + D(g)
Taking A, B and C are in aqueous solution. D being a gas. The reaction is carried out in a close vessel. As reaction proceeds, A and B react to give C and D. As the concentration of C and D increases, they react to give back A and B. Now suppose the reaction is carried out in a open vessel so that the gas D can escape in the atmosphere. So the gas D is no longer available to react with C. So reverse reaction will not occur. The forward reaction is forced to reach 100 %
Let us take another example.
A(aq)+B(aq) C(aq) + D(aq)
Here, D is a volatile liquid. As soon as D is formed, it is removed by distillation. So D is no longer available to react with C. So reverse reaction will not occur. The forward reaction is forced to reach 100 %
Cars up north require more antifreeze than water as a result of the colder
temperature which makes the coolant in vehicles more prone to freezing.
<h3>What is Freezing point depression?</h3>
This is a situation which occurs when solutes are added to a solvent in
order to reduce the freezing point of the solvent. The impurities help lower
the freezing point of the solvent and is commonly used in vehicles.
This is because cars in the North are exposed to colder temperatures
which could freeze the coolant(solvent).

Earth's atmosphere has mainly five layers as
exosphere, thermosphere, mesosphere, stratosphere and troposphere. The
composition of atmosphere is 78 % of N₂,
21 % of O₂, 1 % of Ar and rest
is CO₂ and trace gases.
