Answer to Question #101440 in Physical Chemistry for Abhishek

Question

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

Answer 1

In a mixture of non-reacting gases, the total pressure exerted is equal to the sum of the partial pressures of the individual gases.

PV=nRT

n_total=n_a+n_b+...

P_totalV=n_totalRT

P_total=P₁+P₂+...
