Answer to Question #128218 in Physical Chemistry for Dipu Moni Bora

Question

State Dalton’s law of partial pressure. Derive its mathematical form

Answer 1

Dalton's Law of Partial Pressures. This phenomenon was so significant that it was named after Dalton. It became known as Dalton's Law of Partial Pressures , and it simply states that the total pressure exerted by a mixture of gases is equal to the sum of the partial pressures of each individual gas.

Now multiplying equation (i) by RT/V, we get,

Therefore, P1 = mole fraction × total pressure.

Hence, the partial pressure can be determined by the product of mole fraction and total pressure.
