Answer:
The correct answer is option 3.
Explanation:
The expression of is given by :
Rise in temperature will result in more dissociation of water molecules into hydrogen ions and hydroxide ions.
With an increase in concentration of hydrogen ions and hydroxide ions value of will also increase.
Answer: The correct answer is option B.
Explanation:
Average kinetic energy of the gas molecule is given by relation:
= Avogadro Number
T = Temperature of the gas in Kelvins.
R = Universal gas constant
With increase in temperature the kinetic energy of the gas molecule increases and vice-versa.
So, according to the question the explanation for a drop in temperature of the gas is decrease in average kinetic energy of the gas molecules.
Hence, the correct answer is option B.
