Question

Which one is not correct mathematical equation for Dalton's Law of partial pressure? Here p = total pressure of gaseous mixture

• A. p = p1 + p2 + p3
• B. p = n1($\frac{RT}{V}$) + n2($\frac{RT}{V}$) + n3($\frac{RT}{V}$)
• C. pi = χip, where pi = partial pressure of ith gas; χi = mole fraction of ith gas in gaseous mixture
• D. pi = χipio, where χi = mole fraction of ith gas in gaseous mixture pio = pressure of ith gas in pure state

Answer 1

Answer: (D)

pi = χipio, where χi = mole fraction of ith gas in gaseous mixture pio = pressure of ith gas in pure state

Answer 2

The correct answer is (d).
