What is Dalton's law?

A)
Total pressure is equal to sum of partial pressures
B)
Total entropy is equal to sum of partial entropies
C)
Total number of moles is equal to sum of mole fractions
D)
Total temperature is equal to sum of partial temperatures

Correct Answer :   Total pressure is equal to sum of partial pressures


Explanation : Dalton’s law of partial pressure was formulated to find out the total pressure of the chemically reactive mixture. This is the sum of partial pressures of individual components in the mixture. Dalton’s law is only applicable or perfect gases which means that the intermolecular forces between individual molecules is negligible.
