According to Dalton’s law of partial pressures, _____.

Question

the total pressure exerted by a mixture of unreactive gases is greater than the sum of the partial pressures of the individual gases

the total pressure exerted by a mixture of unreactive gases is less than the sum of the partial pressures of the individual gases

the total pressure exerted by a mixture of unreactive gases is equal to the sum of the partial pressures of the individual gases

none of these

Answer 1

According to Dalton’s law of partial pressures, the correct statement is:

the total pressure exerted by a mixture of unreactive gases is equal to the sum of the partial pressures of the individual gases.

This law states that in a mixture of non-reacting gases, the total pressure is the sum of the pressures that each gas would exert if it alone occupied the entire volume.
