Local winds along the coastal region areas create alternating land breezes and sea breezes during the course of a day. This is a repeating pattern that happens daily worldwide, but only along shorelines. This table shows possible explanations for the breezes. Possible Explanations for Daily Breezes

Explanation

Temperature

Change

Air Over Land

Air Over Water

1

Land heats faster than water during the day

Expands and rises

Denser, causing a low pressure area

2

Water cools faster than land during the night

Expands and rises

Denser, causing a low pressure area

3

Land heats faster than water during the day

Contracts and sinks

Cooler and less dense, causing a high pressure area

4

Land cools faster than water during the night

Contracts and sinks

Warmer, causing a low pressure area

here we have to get the change of moles on decrease the volume of the reaction in gas phase.

the   per the given options it will decrease by (d) 11-50%

we know, on decreasing the volume of the gas phase reaction the reaction moves to the product side.

the reaction:                     so₂cl₂ (g) = so₂ (g) + cl₂ (g)         total

the moles at equilibrium:   1 - α                 α               α           = 1+α

concentrations:                   1 - α               α               α           = 1 + α

(concentration = moles/volume, as volume is 1 l)

(where α is the degree of dissociation)

now the dissociation constant in terms of concentration is :

=  

or,

or,   = (at v = 1l)

the reaction:                     so₂cl₂ (g) = so₂ (g) + cl₂ (g)         total

the moles at equilibrium:   1 - α                 α               α           = 1+α

concentrations:               (1 - α)/0.5           α/0.5         α/0.5       = (1 + α)/0.5

thus, the dissociation constant in terms of concentration is :

or,  

=  

so, the change of 1 : 1/0.5

or, 1: 2

thus it will decrease by 50%.

or, as per the given options it will decrease by 11-50%
