Question

The correct expression of partial pressure in terms of mole fraction is

• A. $P_{1}$ = $x_{1}$ $P_{total},$ $P_{2}$ = $x_{2}$ $P_{total}$
• B. $P=x_{1}$ $x_{2}$ $P_{total}$
• C. $P_{total}$ = $P_{1}x_{1}$, $P_{total}$ = $p_{2}x_{2}$
• D. $p_{1}$+$p_{2}$ = $x_{1}$ + $x_{2}$

Answer 1

Answer: (A)

$P_{1}$ = $x_{1}$ $P_{total},$ $P_{2}$ = $x_{2}$ $P_{total}$

Answer 2

If $x _{1}$ and $x _{2}$ are mole fractions of two gases. Their partial pressures are $p _{1}= x _{1} P _{\text {total }}, p _{2}= x _{2} P _{\text {total }}$
