would increase and 
would decrease.
Explanation:
initially conc. c 0 0
At eqm. 
The expression for dissociation constant is,
for weak acid, 
is very very small , the expression will be,
As 
is directly proportional to concentration, the value of would increase on increasing the concentration.
Thus if would increase, 
would decrease.
It is a weighted average of the atomic masses of the naturally occurring isotopes of the element.

Option c would be the correct answer
<span>Acid rain is precipitation that contains high levels of nitric or sulfuric acid. Natural and industrial sources can release sulfur dioxide and nitrogen oxide into the atmosphere, leading them to combine chemically with oxygen and water to form their respective acidic molecules. These acids are then deposited through rain or dust depending on the climate of the region. While acid rain can occur anywhere in the world, it is prevalent in regions that have high industrial activity.</span>
